SiC FLUORESCENT MATERIAL AND METHOD FOR MANUFACTURING THE SAME, AND LIGHT EMITTING ELEMENT |
| 摘要 |
Provided are a SiC fluorescent material with improved luminous efficiency, a method for manufacturing the same and a light emitting element. A SiC fluorescent material comprises a SiC crystal in which a carbon atom is disposed in a cubic site and a hexagonal site, and a donor impurity and an acceptor impurity added therein, wherein a ratio of a donor impurity to be substituted with a carbon atom in a cubic site to a donor impurity to be substituted with a carbon atom in a hexagonal site is larger than a ratio of the cubic site to the hexagonal site in a crystal structure. |

1. A SiC fluorescent material comprising a SiC crystal in which a carbon atom is disposed in a cubic site and a hexagonal site, and a donor impurity and an acceptor impurity added therein,
wherein a ratio of a donor impurity to be substituted with a carbon atom in a cubic site to a donor impurity to be substituted with a carbon atom in a hexagonal site is larger than a ratio of the cubic site to the hexagonal site in a crystal structure. |
