Rare earth glow in the dark material

Rare earth luminescent rare earth 4f electrons by leaping between different energy levels arising due to the excitation of different ways, can be divided into light-emitting photoluminescence (photoluminescence), cathodoluminescence (cathodluminescence),glow in the dark dye , electroluminescence (electroluminescence), Radioluminous (radiation luminescence), X-ray luminescence (X-ray luminescence), friction luminescence (triboluminescence), glow in the dark rock ,chemiluminescence (chemiluminescence) and bioluminescence (bioluminescence) and so on.

Rare earth luminescent with the absorption ability, high conversion efficiency, can emit light from the ultraviolet to the infrared spectrum,glow in the dark material , especially in the visible region has a strong launch capability and so on. Rare earth luminescent materials have been widely used in various aspects of imaging displays, new light, X-ray intensifying screens and so on.
