luminescent material is to be found Photoluminescent Tape

The new long afterglow luminescent material is to be found in the nineties, it is completely different from the traditional type of sulfide-and radiation-excited luminous material does not contain any harmful elements, stable performance, 

Afterglow long time. Aluminosilicate ceramic material such phosphorescent pigment‍ as the matrix material to form a rare earth element-doped luminescent centers and trapping centers, the display having a good night. In this New types of long afterglow luminescent materials mainly to a variety of adhesive materials can be made into various forms of nighttime display or decorative devices. For example: Mixed coated with transparent sintered ceramic powder, made ??from 

Luminescent ceramic; masterbatch added to the photochromic sheets‍ light-emitting plastic granules, plastic sheet, or may be made of a light emitting film; mixed with the transparent resin or adhesive, use can be made of various paints or coatings 

Due to the long afterglow luminescent Photoluminescent Gravel

Due to the long afterglow luminescent material removal can be light illumination in the dark a long time, so people will this material colloquially known as "luminous." Traditional luminous two categories: sulfur Compound-and radiation-excited type. photoluminescent paint‍ Sulfide including ZnS, CaS, etc., and chemical properties of these materials are relatively less stable in water and ultraviolet light easily hydrolyzed or photolysis, Afterglow time is generally two to three hours, life is also shorter. Excitation radiation type is incorporated into radiant energy emitted by radioactive substances within the material as an excitation source, excitation and emission center Glow. Because such materials containing radioactive substances harmful to the environment and human health, Photoluminescent Ceramic‍ has been banned in most countries use. 

luminous materials are Photoluminescent Rigid Sheet

Long Afterglow 

Long-lasting storage luminous materials are photoluminescent (Photoluminescence) of a material, the excitation energy is the energy that can be any kind of ambient light, such as: sunlight, lighting, etc. 

. The basic principle of this luminescent material is: photoluminescent pigment suppliers‍ a material preparation process, the doped luminescent center-forming element in the matrix and the center of the trap, when excited by external light, the light emitting center Electronic ground state to an excited state, when the electron transition from the excited state to the ground state, light emission is formed. Meanwhile, some of the electrons in the excited when falling into the trap center is bondage. After removal of light , Disturbed by ambient temperature, bound to fall into the trap out of the trap-state electronic energy released to stimulate the formation of a light emitting luminescent center. Since the electron is bound to trap affected by ambient temperature Disturbance Photoluminescent Ceramic‍ gradually out of the trap, so luminous performance of a lengthy process, which formed a long afterglow.

Afterglow phenomenon photoluminescent pigment

Afterglow phenomenon 

If the fluorescent material contains some trace impurities, and these levels of impurities located in the forbidden band, the equivalent of trap levels, 

After being excited from the valence Photoluminescent Tumbled Gravel‍ band into the conduction band electrons, will fall into the trap levels. Because these are captured by the trap levels must first excited electronic trap levels out after the transition back into the conduction band to the valence band, so they are incident photon excitation luminescence will be delayed for some time, the emergence of the so-called afterglow phenomenon. 

Afterglow generation principle 

Afterglow generation principle 

Long-lasting and can be divided into short afterglow afterglow, they are determined by the delay time. 

Is the photoluminescent material in the light emitting material (usually ultraviolet light, infrared light and visible light) emitting excitation irradiation. Relaxation time glow in the dark pigments‍ classified according to light, the photoluminescent material can be divided into two types of fluorescent materials and phosphorescent materials. They correspond to the above short and long afterglow afterglow. 

Photoluminescence mainly three-step process: 

1, the absorption of a photon; 2, the laser can be transferred to the fluorescent centers; 3, the radiation emitted by the fluorescent centers. 

Photoluminescent material is mainly used for display, imaging, lighting and everyday life. In everyday products, such as washing brighteners, fluorescent paint, fluorescent cosmetics, and so the use of the fluorescent dye a fluorescent material. Some lamp phosphor materials are phosphorescent glow in the dark pebbles‍ material, which can be made with high efficiency and high color rendering fluorescent lamps.

EL sheet referred to el Photoluminescent Tumbled Gravel

EL sheet referred to el (Electro Luminescent electrical excitation light). Cold light emitting material is the working principle (Phospher Partides) sulfide particles sandwiched by bipolar AC voltage generated by AC electric drive, high speed Photoluminescent Gravel‍ electronics within the light emitting layer, a light emitting atom activated to obtain sufficient energy to be accelerated , field electron collision excited fluorescent material and the light emission center, the resulting electron energy pole jump - Change - resulting composite efficient luminescence emitted a physical phenomenon that electrical excitation phenomena. 

In need of special light sources (eg: no shadows, no photoluminescent paint‍ dizzying, brightness uniformity and neon effect ......), in with the environment needs (eg: a narrow space, complex shapes, temperature and power consumption constraints, vibration Under the environment ......), the illusion is impossible to make up the traditional cold light source. In addition, for printed mark, instructions, election propaganda, body decoration and interior design, photo or text on Glow in the dark materials‍ backlit transparent advertising material, EL cold light is the best light materials. 

What is the principle of luminous road photoluminescent pigment

Netherlands magical luminous paint can put to use to replace street lights? 

According to the BBC recently reported that Photoluminescent Gravel‍ the Dutch 500-meter long section of the highway will be the end of the light-emitting into the trial. The N329 road near Oslo City Highway, road markings using fluorescent paint, after charging in daylight, at night more than eight hours of continuous green fluorescence, thereby replacing the lights. 

The designer of the road expressed the hope that through this program to save energy, reduce costs and improve road safety purposes. 

Questions: 

What is the principle of luminous road? What's the difference with the traditional road reflective logo? It really can save energy and replace street lights? 

Answer: 

According to media reports, the nature of the road is the use of light-emitting a glow in the dark fluorescent powder to make signs, the roads automatic light. 

Road use light-emitting phosphors are long afterglow luminescent powder." Recently, Professor of Shanghai Jiaotong University Daide Chang told reporters that this material can absorb sun light during the day, at night and gradually release the green light. 

The material is sent only light in a dark environment, the eyes can be felt during the day feel." Professor of Chemistry and Molecular Engineering, East China University of Technology Shen Yongjia further explained to reporters, also called afterglow luminescent powder luminescent materials, in natural light irradiation, or other artificial light sources that can store energy of the external optical radiation, and at a photoluminescent paint‍ temperature (room temperature) and for a long period of time to slowly release the stored energy in the form of visible light luminescent materials. 

It is understood that since has good luminescent properties, since the 1990s, long afterglow luminescent powder began to receive widespread attention, and began to apply at night signs, emergency lighting and light-emitting ceramic. 

In China, the ground reflective logo has been an important means of auxiliary lights. By car lights, the driver can generally see the road. Then, add the mark compared to the way long afterglow luminescent powder, both of which have anything different? 

Daide Chang said that the main difference between the two is that one is self-luminous, a passive reflector. "Active glowing effect to be significantly better than conventional reflective effect, traffic safety has been significantly improved." 

In addition, the effect of long afterglow luminescent powder, the report pointed out that it can continue to light in the dark eight hours, in order to protect the lighting needs of the night, you can replace the lights. 

However, Shen Yongjia had a different opinion. "Based on its performance, luminous powder luminous at night only last about four to five hours." Shen Yongjia said, from the continuous emission time, it does not guarantee a night lighting. 

In addition, he said, adding a luminous pink road signs only a faint green, can not achieve adequate lighting effect. "This suit is not installed street lights in the field road use, traffic can be set to identify the scope, not to put the car into the ditch." 

also pointed out that luminous paint painted road lane for the region, street lighting between the lane marking can be covered, the use of light-emitting powder coating can not. 

At the same time, cost and stability of the luminous road has also been questioned scholars. 

The key element of long afterglow luminescent powder is rare." Shen Yongjia said before the rare earth prices, the domestic price of 1 kg flour is about 1,000 to 2,000 yuan, and now the price should be higher. 

Efficiency luminous pink haze on cloudy days to Glow in the dark materials‍ absorb energy and how high? Absorption efficiency is not high enough in the circumstances, how to ensure continuous light at night?" Experts believe that the luminescence on the road should be further stability and luminous efficiency research and planning. 

the current luminous paint Photoluminescent Rigid Sheet

However, the current luminous paint application is still in the exploratory stage, according to its performance, luminous powder luminous at night only last about Photoluminescent Gravel‍ four to five hours. From the continuous emission time, it does not guarantee a night lighting. In addition, the range of luminous paint lighting also needs to be improved. Luminous paint painted road lane for areas between street lighting lane marking can be covered using a paint luminous powder can not. In addition, cost and stability of luminous road is also in the demonstration phase, therefore, on the whole it seems, there is still a kind of luminous paint more conceptual product, from its large-scale promotion and application is still a long way to go. 

Champoux consulting release of Photoluminescent Tumbled Gravel‍ hina specialty coatings industry development prospects and investment risk research report" shows: luminous paint is still experimental and exploratory stage, light road should be further research and planning on the stability and luminous efficiency discussion and study many problems, therefore, has not yet reached a consensus to deal with the next stage, contributed to the early large-scale application of luminous paint.
