Photoluminescent Tumbled Gravel for marking the pathway

The Photoluminescent Tumbled Gravel is based on the synthesis of photoluminescent pigments and synthetic resins. When the light source is exposed, photoluminescent pigments absorb light energy and spend the night. A light stone can be used as a pebble paving or a loose addition to a gravel path. The glowing stone enhances security by marking passages at night.

High initial brightness and long afterglow photoluminescent pigments

Long-afterglow fluorescent pigments is made by firing mixture of alumina and rare earth raw material.Afterglow can be maintained for more than 12 hours.It is non-toxic non-radioactive.photoluminescent pigments can be easily mixture with all kinds of chemicals with good durability and stability.The luminescence and shining process can be repeated for unlimited times.It has the features of high initial brightness and long afterglow and will provide convenience and security to all industries.

The effect of photoluminescent tumbled gravel

Photoluminescent stone gravel is a man-made glowing stones, based on Photoluminescent pigment and ceramics. When exposed to light sources, the photoluminescent pigments inside Luminous crushed stones become excited and glow in the dark with very stronger initially , then reducing slowly overnight. The glow is best seen in a dark area, where ambient light sources such as streetlights and moonlight are absent. Luminous crushed stones are used in Concrete, Pavers and marble products as an exposed aggregate. Luminous crushed stones enhance safety by marking the pathway in Low Light Level conditions. In daylight the Luminous crushed stones have a slight white to green color and can be supplied in after-glow colors of yellow-green, blue-green and sky blue.With the beautiful decorative glow effect and safety direction function, glow stones are suitable for many application area.It can be used in footpaths, gardens, rockeries, pebble paths, terrazzo concrete, driveways and so on. Spreading around the swimming poor,putting in the aquarium or inlay into the scenery wall all are the good idea for us to decorate the new house.

A kind of rigid plastic board-photochromic sheets

Photochromic sheets is a kind of rigid plastic board.It is made of photoluminescent pigments that with non-toxic and harmless and no radioactivity. It belongs to long after-glowing display board with excellent comprehensive advantage. This sheet can be cut into all kinds of shapes. It can be fixed on surface of normal object. It can be printed design on the surface by silk screen printing or other ways, to engender background glow.

The Specific Information photoluminescent pigment

1).The bigger the pigment's particle size, the better luminance it will be.Please choose the bigger particle size photoluminescent pigments on the condition that your technology or manufacturing process permitted.

2).The PH value of the pigment is around 10-11, it will be hydrolysis and loss luminance if used in water based material directly.To avoid this, we coated the pigments with special glow in the dark material. Please choose our coated pigment when used in water based material.

3).Avoid to contact the pigment with metal. Due to the friction with metal,it will turn into black and loss luminance since it contains aluminum.

Light board is a transparent plate member

A light emitting film, primarily by a light plate, a light reflecting film, and a light emitting element composed of a transparent optical plate is a plate member, the periphery where appropriate light-emitting element is provided with an available set of installation holes. The optical plate receiving hole periphery the other is provided with a guide optical slot and through the light guide groove is set and the surround the light glow in the dark material and the receiving hole of the outer side, thereby forming as an optical cell, the last of the light plate bottom edge, plus There is a reflective film, reflective film, and through which the light guide with the grooves, when the light emitting element emits light, the light guide groove by setting to the light source and photoluminescent pigments of the light guide plate groove periphery, and then the center of the guide plate to the light reflectors and light board can show full glow effect. The utility model has the advantage of not using the cold plate in the way and still emitting light with high quality and reduce costs.

Preparation of light- emitting material good performance

Sol - gel (So1-ge1) method is a very broad application prospects of nano- powder synthesis method , its main advantage is that at lower temperature synthetic products , and products with small particle size uniformity is good.Phosphorescent sand this SrAl2O4: Eu2 +, Dy3 + , the precursor material is an organic compound solution containing aluminum , with activator of activator, flux , catalyst compounds are organic solutions or aqueous mixture , water was added , remain in solution 2 ~ 3d, to form a gel , drying , removal of organic material , after ignition , and photoluminescent pigments N2 + H2 atmosphere ignition reduction derived carbon storage material . Sol - gel method can be prepared very good performance at the light emitting material , the reaction can be well controlled.

salts luminescent material characteristics

Rare earth activated alkaline earth metal aluminate luminescent material is a rare earth Eu especially on the active element , an alkaline photoluminescent pigments aluminate to a class of luminescent substrate material . Where Eu and Dy co-activated strontium aluminate SrO · nA12O3: Eu, Dy is a typical representative of the 20th century, it was developed in the early 1990s, a new class of luminescent material activated alkali earth aluminate luminescent materials are characterized from beginning high brightness, long afterglow time (> 12h), non-radioactive hazards, resistance to environmental erosion, known as the green energy-saving materials . Glow in the dark tape: Eu, Dy emitting material , with the SrO/A12O3 ratio, the fluorescence wavelength and afterglow time is different , the SrO · A12O3: Eu, Dy, a yellow- green light after excitation , peak wavelength 520nm; 2SrO · 3A12O3: Eu, Dy, excited by blue-green light , the peak wavelength of 490nm. The afterglow time is longer than the latter the former, but the initial luminous intensity is the opposite .
