Long-lasting light-emitting material

powdered paint pigments glass material refers to glass or glass products have long-lasting light-emitting properties. Luminescent glasses while having a long-lasting light-emitting materials and crystal glass long range disorder characterized by short-range order of amorphous. After excitation light, in the dark to produce Afterglow emission spectra from 440 ~ 650rim, can achieve white light color, purple, blue-purple, blue, cyan, green, yellow-green, yellow, orange, red. Emitting mechanism of light emission mechanism can draw Long Afterglow explained mainly by the material of rare earth ion activation energy transition produces a long-lasting phenomenon.
