Photoluminscent powder divided into spontaneous light energy storage type photoluminscent powder and photoluminscent powder with radioactive two categories.
Energy storage type self-illumination photoluminscent powder luminescent principle, simple, luminous powder is after the light irradiation, the light energy storage, and then converted into light energy released, its characteristic is luminous intensity attenuation fast, short duration.
Radioactive photoluminscent powder luminescent principle, it is in the fluorescent powder mixed with radioactive material, using the rays from radioactive substances continuously stimulate phosphor luminescence, its characteristic is luminous intensity is relatively stable, shine for a long time, but there is radioactive, not suitable for civilian use.
We use the former, energy storage type self-illumination noctilucent powder, non-toxic, harmless, no radioactive.
