photoluminescent pigment as a powder photoluminescence storing luminous material

photoluminescent pigment as a powder photoluminescence storing luminous material. Typically, a small amount of flux (such as sodium chloride) and a trace amount of activator is transferred from zinc, calcium, barium or strontium sulfide from the blue to the red part, with copper as the activator is transferred from the green to the red part. The pigment proportion, note the use of mix.
It should be stored in ventilated, dry environment, pay attention to moisture, failed once finished using phosphorescent pigment should note sealed. Metallic materials have a greater influence on the luminescent properties, should avoid contact with metal materials.
