| titleOfInvention | Fluorescent ceramic with aluminum oxynitride matrix and preparation method therefor |
| abstract | Provided is a multiphase fluorescent ceramic. The multiphase fluorescent ceramic comprises an aluminum oxynitride phase (3) as a matrix phase, a phosphor powder (1) uniformly distributed in the matrix phase, and an alumina phase (2) mixed with the phosphor powder (1) and the aluminum oxynitride phase (3). In the method for preparing the multiphase fluorescent ceramic, a surface of the phosphor powder (1) or the aluminum oxynitride (3) is coated with a layer of alumina, and is then sintered and combined with aluminum oxynitride or the phosphor powder (1), to form the multiphase fluorescent ceramic. Alternatively, the aluminum oxynitride, the aluminum oxide, and the phosphor (1) are uniformly mixed and subjected to ball milling and then sintered together to form the multiphase fluorescent ceramic. The multiphase fluorescent ceramic is a fluorescent ceramic having high luminous efficiency, high thermal conductivity, excellent thermal shock resistance, and excellent mechanical strength. The multiphase fluorescent ceramic is excitable by a high-power excitation light source to realize a semiconductor light source with a high brightness, such as a high-power white LED light source or a blue laser light source etc. |
