lighting and other energy excitation

with the development and progress of science and technology , the emergence of new storage realglow ornamental gravel light rare earth -based alkaline earth aluminate phosphor material does not contain radioactive material. It differs from the traditional nature of the sulfide -and radiation- excited type luminous material , completely free of any harmful elements , chemically more stable, high brightness, long afterglow time . photochromic sheets storage luminescent material is a light-induced luminescence (Photoluminescence) material by ambient light , such as any kind of daylight , lighting and other energy excitation .
