Luminous light-emitting principle simply put, is the absorbance - light, this process can be infinite loop, so luminous powder luminous performance is permanent.
Just the process of absorbing energy reserves, is emitting energy release process. luminous pigment with mobile phone batteries are the same as storage products.
Long luminous powder absorbance 15-30 minutes (depending on light intensity different) so that energy can achieve a relatively saturated, the same as the phone battery is fully charged. At this point the best luminous masterbatch. Short-acting luminous light energy to make it 1-5 minutes to saturation.
