The main classification of luminescent material

A luminescent material is varied, the main types are: photoluminescence, cathode luminescence, electroluminescence, thermoluminescence, optically stimulated luminescence, luminescent
The fluorescent material
1 molecular structure of the problem
The fluorescent material is some sensitive special photosensitive molecules, already exists in the form of photographic materials and molecular inertia, when the absorption light irradiation he is not our long said, but the light energy to the molecular structure of photosensitive material change, light to structure irradiated molecules continue to change until it best change, when there is no light, there is no external energy is its molecular structure continues to change, because the structure of molecular interactions between inertia to restore, restore time to produce energy, this is the light into.
2 no matter how some fluorescent material irradiation (visible light) will not light, but in some special ray (Ray) exposure to light, when the molecular photosensitive material by a ray irradiation, molecular atoms from the structure will not change, ray itself with large amounts of energy, atomic by the radiation force electronic around the nucleus of easily escape
So put some invisible rays through the electronic force changed their frequency so that the wavelength and frequency in the range of visible light, this is the luminous principle, we cathode ray picture tube commonly used is the use of this principle.

The difference and connection between the light emitting materials and fluorescent powder

glow in the dark material refers to the excitation source for the ultraviolet, visible light, the excitation source material capable of emitting light. In accordance with the luminescence decay time can be divided into long afterglow luminescent material and luminescent materials. Long afterglow luminescence materials, just be excited source for a period of time, and then disconnect the luminescence excitation source still light emitted, the general decay time is larger than Ms.

photoluminescent paint and screen printing inks

Neutral or alkaline transparent resin should be used.
Photoluminescent pigment avoid using metal containers and processing equipment.
Coatings should be noted that the finished product and the moisture content of the ink , the higher the moisture content , the shorter the storage time .
Use high- viscosity resin , and add anti-settling agent to prevent precipitation occurs .
Stir before using uniform finished product that can be used to adjust the viscosity of the diluent , but can not use heavy metal compounds as additives.
Printing is recommended to use a white or reflective background color , can increase the brightness of the printed pattern .
Screen printing is photoluminescent pigment mesh 80 to 120 mesh .
Paint or ink when the coating thickness 120μm best.
Luminous recommended dosage is 20 % to 40%
Printed material is different , you should choose a suitable base paint or ink .

phosphorescent sand production and export

China has become the world's largest carbon black producer and consumer . However, in high-performance and specialty carbon black products, almost all of China's dependence on imports . Carbon black industry will make every effort to achieve the production of power shift realglow gravels for sales the production of power . This is the reporter from March 23 to 25 , held in Xi'an in 2010 from the China Rubber Industry Association Annual Conference and black club members learned information sessions . It is understood that China currently has about 100 carbon black business , with an annual capacity of more than 430 million tons in 2009 , 2.7 million tons of carbon black production . However, the majority of SMEs in the industry , industry concentration is poor, realglow gravel driveway in lack of research funding , new product development lags behind. Although there are a large number of annual exports of low-end products , but high performance and specialty carbon black products are almost entirely dependent on imports .

Polymer light -emitting materials with hair
Luminous plastic luminescent material is a class of light-emitting polymer composites agent . After external Realglow photochromic pigments can emit light emitting longest time has been developed up to 70h or more, also known as luminous afterglow luminescent material . After the withdrawal of foreign sources , the energy stored in the excitation can be light for the dark indicate functional and decorative features . Polymer light-emitting realglow decorative stone is a high value-added new functional materials rise in recent years , especially organic electroluminescent materials have become a research topic of concern , and the inorganic semiconductor electroluminescent material compared with polymer electroluminescence low-voltage DC drive, high brightness, high efficiency and other advantages. Alkoxy as the poly (PPV), realglow pigments in paint carbazole (PVK). Its price is cheap , simple production process, and has good mechanical properties, good processing properties and thermal stability, outstanding advantages of these polymers will undoubtedly become the most commercial power promising luminescent material.
