Abstract
A luminescent element includes a luminescent glass and a metal layer with a metal microstructure formed on a surface of the luminescent glass; wherein the luminescent glass has a chemical composition: bY2O3.cAl2O3.dB2O3.yTb2O3, wherein bY2O3.cAl2O3.dB2O3.yTb2O3. A preparation method of a luminescent element and a luminescence method are also provided. The luminescent element has good luminescence homogeneity, high luminescence efficiency, good luminescence stability and simple structure, and can be used in luminescent device with ultrahigh brightness.
