LIGHT EMISSION APPARATUS AND MANUFACTURING METHOD THEREOF

摘要

A light emission apparatus (10) and a manufacturing method thereof are provided. The light emission apparatus includes a light emission base body (13) and a metal layer (14) with metal microstructure. The metal layer is set on the surface of the light emission base body. The material of light emission base body is transparent ceramic Y 3 Al 5 O 12 :Tb. By setting a metal layer with metal microstructure on the light emission base body, the interface between the metal layer and the light emission base body could form a surface plasmon under the cathode ray (16). The spontaneous emission of the transparent ceramic and the emission efficiency of the light emission base body could be enhanced by the effect of surface plasmon.
