Various specifications photoluminescent powder

Long-term luminescent storage pigment is also known as rare earth material long afterglow storage powder. This kind of material in the synthesis process of the crystal lattice to produce structural defects and impurity defects have luminous properties, by the material lattice defects caused by the light is called self-excited light, and by the impurity defects caused by the light is called activated light, the actual application of various types of luminous materials are mostly the latter. This product is non-toxic, harmless and non-radioactive. Luminous powder luminescence is based on the principle of photoluminescence, its excitation light source is generally daylight and artificial light source, it absorbs the excitation of light energy and stored, after the light excitation stops, and then the stored energy in the form of light slowly released. This luminous material will glow in the dark environment without external light sources, and its luminous time is called the afterglow time. Among the long afterglow materials with good performance, there are silicate system long afterglow materials with various luminous colors, etc., and the alkaline earth aluminate activated by rare earth has the best afterglow characteristics, which can achieve more than 12 hours of afterglow.

Application: Long lasting light storage powder as an additive, can be evenly distributed in: paint, ink, paint, plastic, flower pulp, ceramics, glass, fiber and other transparent media, to achieve the luminous function of the medium. It is characterized by showing its own appearance color in the light, and emits different colors of light in the dark after absorbing light, showing good low-illumination emergency lighting, indicating signs and decorative beautification functions. Various luminous products made with the pigment are widely used in daily consumer goods such as clothing, shoes and hats, stationery, clocks, switches, signs, fishing gear, toys, crafts and sporting goods. And in building decoration, transport vehicles, military facilities, fire emergency systems such as: import and export signs, escape route indication system has a good role.
