Abstract
A luminescent element including nitride includes a luminescent film and a metal layer with a metal microstructure formed on a surface of the luminescent film; wherein the luminescent film has a chemical composition: Ga1-xAlxN:yRe, wherein Re represents the rare earth element, 0≦x≦1, 0<y≦0.2. A preparation method of a luminescent element including nitride and a luminescence method are also provided. The metal layer is formed on the surface of the luminescent film, and the luminescent element including nitride has simple structure, good luminescence homogeneity, high luminescence efficiency, and good luminescence stability.
Claims3
