Fluorescent ceramic, preparation method thereof, light source device and projection device
The invention provides fluorescent ceramic, a preparation method thereof, a light-emitting device and a projection device. The fluorescent ceramic comprises an alumina matrix phase and light-emittingcenters uniformly dispersed in the alumina matrix phase, and the fluorescent ceramic is characterized in that the light-emitting centers are spherical fluorescent single crystal particles, and the spherical fluorescent single crystal particles have smooth spherical outer surfaces. The spherical fluorescent single crystal particles have regular spherical shapes and smooth outer surfaces, so that the original appearance can be kept after sintering, the structural strength of the sintered fluorescent ceramic can be improved, and in addition, the luminous efficiency of the fluorescent ceramic canbe further improved by the spherical fluorescent single crystal particles with a larger particle size range.
本发明提供了一种荧光陶瓷及其制备方法、发光装置和投影装置，所述荧光陶瓷包括氧化铝基质相及均匀分散于氧化铝基质相中的发光中心，其特征在于，所述发光中心为球形荧光单晶颗粒，所述球形荧光单晶颗粒具有光滑的球形外表面。所述球形荧光单晶颗粒具有规则的球形形状和光滑的外表面，从而在烧结后能够保持原有样貌，有利于烧结后的荧光陶瓷的结构强度的提高，另外本发明更大粒径范围的球形荧光单晶颗粒，可进一步提高荧光陶瓷的发光效率。
