| 摘要 |
A white light-emitting device of the present invention includes a substrate (101); a diamond semiconductor layer (105) provided on the substrate (101), in which one or a plurality of p-type ± layers (102), a p-type or n-type ³ layer (103), and one or a plurality of n-type ² layers (104) are laminated in this order from the substrate (101); a first electrode (106) provided on the ± layer (102) which injects an electric current; a second electrode (107) provided on the ² layer (104) which injects an electric current; and a fluorescent member (108) which coats a light emission extraction region of the surface of the diamond semiconductor layer. |
