Rare earth luminescence is generated by the jump of rare earth 4F electrons in different energy levels. Due to different excitation modes, luminescence can be divided into photoluminescence, cathode ray luminescence, electroluminescence, radioactive luminescence, X-ray luminescence, tribluminescence, chemiluminescence and bioluminescence.

Soil luminescence has strong absorption ability, high conversion efficiency, and can emit the spectrum from ultraviolet to infrared light, especially in the visible region has strong emission ability and other advantages. Rare earth luminescent materials have been widely used in display, new light source, X-ray brightening screen and other aspects.

Rare earth luminescent materials have narrow hair spectrum, high color purity and bright color. High light absorption capacity, high conversion efficiency; The emission wavelength distribution area is wide. The fluorescence lifetime ranges from nanoseconds to milliseconds, up to six orders of magnitude. Stable physical and chemical properties, high temperature resistance, can withstand high power electron beam, high-energy radiation and strong ultraviolet light.

It is these excellent properties that make rare earth compounds become the main research objects to explore high-tech materials
