Abstract:
1. A method for making a light emitting diode, comprising: providing a substrate having an epitaxial growth surface; growing a first semiconductor layer on the epitaxial growth surface, an active layer on a surface of the first semiconductor layer, and a second semiconductor layer on a surface of the active layer in sequence, wherein the first semiconductor layer, the active layer, and the second semiconductor layer cooperatively constitute a source layer; forming a metallic plasma generating layer on a surface of the second semiconductor layer away from the substrate; disposing a first optical symmetric layer on a surface of the metallic plasma generating layer away from the substrate, and a second optical symmetric layer on a surface of the first optical symmetric layer away from the substrate, wherein a refractive index difference between the first optical symmetric layer and the source layer is less than or equal to 0.3, and a refractive index difference between the substrate and the second optical symmetric layer is less than or equal to 0.1; and applying a first electrode electrically connected with the first semiconductor layer, and applying a second electrode electrically connected with the second semiconductor layer.
