<p>A light emitting device and a manufacturing method thereof are provided. The light emitting device (10) comprises a light emitting substrate (13) and a metal layer (14) having irregularly arranged nano-particles structure formed on a surface of the light emitting substrate (13), wherein the material of the light emitting substrate (13) is a transparent ceramic (13) comprised of Y 2 O 3 :Eu. By disposing the metal layer having the irregularly arranged nano-particles structure on the light emitting substrate, surface Plasmon is formed on the interface between the cathode ray and the light emitting substrate, to greatly increase the light efficiency.</p> |
