| 简介 |
Provided is a fluorescent material which has improved water resistance, ultraviolet light resistance, etc. and with which life prolongation can hence be achieved. Also provided is a luminescent device. The fluorescent material comprises particles (11) of a fluorescent substance and a coating layer (12) with which the whole surface of each fluorescent-substance particle (11) has been covered, the coating layer (12) comprising at least one metal oxide selected from a group consisting of rare-earth oxides, aluminum oxide, composite oxides of yttrium and aluminum, magnesium oxide, and composite oxides of aluminum and magnesium. The fluorescent material hence has improved water resistance, ultraviolet light resistance, etc., and is capable of life prolongation. |
