FLUORESCENT CERAMIC AND PREPARATION METHOD THEREFOR, LIGHT-EMITTING DEVICE, AND PROJECTION DEVICE
Disclosed are fluorescent ceramic and a preparation method therefor, a light-emitting device, and a projection device, relating to the technical field of fluorescent ceramics. The fluorescent ceramic at least comprises: a matrix (101); and light-emitting centers (102), first scattering units (103) and second scattering units (104) which are distributed in the matrix (101), with the refractive index of the first scattering unit (103) being greater than that of the light-emitting center (102), and the refractive index of the second scattering unit (104) being less than that of the light-emitting center (102). In this way, the fluorescence scattering performance of the fluorescent ceramic can be improved, thereby increasing the lighting effect and utilization rate in a light source system.
