Glow Pigment
Introduction of Glow pigments
Photoluminescent pigment is also known as a long-lasting photoluminescent pigment, luminous pigment, luminescent pigment, phosphorescent pigment, glow pigment, glow in the dark pigment.

Types of glow pigments
There are 2 types of glow pigment: one is an alkaline earth aluminate-based long afterglow photoluminescent material activated by rare earth elements, and the other is traditional sulfide-based photoluminescent material, Particularly, the alkaline earth aluminate photoluminescent material can absorb various visible light which wavelength less than 450nm for 10-20 minutes and then emit light continuously for over 12 hours in the dark. The luminosity and its glow time are 30 times more than traditional luminous materials represented by ZnS:Cu; and its light absorption, storage, and emission capabilities can be recycled.

Remark
⑴The unit of particle size is μm. The particle size is expressed by Medium Particle size (D50).
⑵The unit of afterglow brightness is mcd/m2. All the tests are executed according to the standard of DIN67510, which is to detect the afterglow brightness of the sample for 10 min excited by D65 standard light source illumination of 1000LX for 5 min.
