Everluminous products co sell glow in the dark powder .I. Intruduction The rare earth-activated alkali earth aluminate-silicate photoluminescent pigment compounded by high-temperature solid phase reaction, is a novel, long-efficiency and environmentally friendly material. II. Product characteristics1. 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.
