The difference and connection between the light emitting materials and fluorescent powder

glow in the dark material refers to the excitation source for the ultraviolet, visible light, the excitation source material capable of emitting light. In accordance with the luminescence decay time can be divided into long afterglow luminescent material and luminescent materials. Long afterglow luminescence materials, just be excited source for a period of time, and then disconnect the luminescence excitation source still light emitted, the general decay time is larger than Ms.
