I. Intruduction
The rare earth-activated alkali earth aluminate-silicate photoluminescent pigment, with the chemical formula of  , compounded by high-temperature solid phase reaction, is a novel, long-efficiency and environmentally friendly material.
II. Product characteristics
1. Photoluminescent pigment is a light-yellow powder, turns to green color after being excited by light.
2. The smaller the particle size,the lower the luminance is.
3. Compared with other pigments, photoluminescent pigment can be easily and widely used in many fields.
4. High initial luminance, long afterglow time (Test according to DIN67510 Standard, its afterglow time can be 10,000 minutes)
5. Its light-resistance, aging-resistance and chemical stability are all good (more than 10 years of life span)
6. It is a new type of environmentally friendly photoluminescent pigment with the characteristics of non-toxicity, non-radioactivity, non-flammability and non-explosibility.
III. Application Scope
It can be used in many transparent or translucent media, such as plastic, paint, glaze, ink, glass, printing slurry etc. to produce luminous products. With the good indicating and beautifying effect in darkness, it can be widely used in emergency signs, passway signs, switches, enamel nameplate, road signs, toys, handicraft, clock, meter panels ,textile, firemen's equipment, military and camp instruments etc.
