Multiphase fluorescent ceramic and preparation method thereof
The invention relates to a multiphase fluorescent ceramic and a preparation method thereof. The multiphase fluorescent ceramic comprises a high-thermal-conductivity dielectric ceramic matrix and fluorescent ceramic main bodies which are distributed in the high-thermal-conductivity dielectric ceramic matrix and are periodically arranged; the shortest distance L between the adjacent fluorescent ceramic main bodies is 200-1000 microns, and the volume fraction delta of the high-thermal-conductivity dielectric ceramic matrix in the multiphase fluorescent ceramic is 5-60%; the fluorescent ceramic main body is rare earth doped transparent ceramic; and the material of the high-thermal-conductivity dielectric ceramic matrix is selected from at least one of Al2O3, AlN, BeO, Sc2O3, Si3N4, BN, SiC andMgO.
本发明涉及一种复相荧光陶瓷及其制备方法，所述复相荧光陶瓷包括：高导热介质陶瓷基体，以及分布在高导热介质陶瓷基体中的呈周期排布的荧光陶瓷主体；相邻荧光陶瓷主体之间的最短距离L为200～1000μm，高导热介质陶瓷基体占复相荧光陶瓷的体积分数δ为5～60%；所述荧光陶瓷主体为稀土掺杂透明陶瓷；所述高导热介质陶瓷基体的材料选自AlO、AlN、BeO、ScO、SiN、BN、SiC和MgO中的至少一种。
