The invention discloses a high-stability fluorescent ceramic for high-power laser illumination. The fluorescent ceramic comprises single-phase fluorescent particles, wherein the chemical formula of the single-phase fluorescent particles is (Ce[x]Tb[y]Lu[z]Y[1-x-y-z])3Al5O12, x is more than or equal to 0.001 and less than or equal to 0.01, y is more than or equal to 0 and less than or equal to 0.4,and z less than or equal to 0 and less than or equal to 0.4. The high-stability fluorescent ceramic has the beneficial effects that the test of a light-emitting device with controllable irradiation power density proves that the phosphor has excellent light-emitting efficiency and stability, and can meet the requirement of high-power laser lighting application.
本发明公开具有高稳定性的大功率激光照明用荧光陶瓷，包含有，荧光陶瓷含有单相荧光颗粒，单相荧光颗粒的化学式为(CeTbLuY)AlO，其中，x、y、z的取值范围为：0.001≤x≤0.01，0≤y≤0.4，0≤z≤0.4。本发明的有益效果在于：经辐照功率密度可控的发光装置测试验证，荧光体具有优异的发光效率和稳定性，可以满足大功率激光照明应用。
