Fluorescent ceramic, preparation method thereof, light-emitting device and projection device
The invention relates to the technical field of fluorescent ceramics, and particularly discloses a fluorescent ceramic, a preparation method of the fluorescent ceramic, a light-emitting device and a projection device. The light-emitting center, the first scattering unit and the second scattering unit are distributed in the matrix; the refractive index of the first scattering unit is greater than that of the light-emitting center; the refractive index of the second scattering unit is smaller than that of the light-emitting center; the absolute difference between the refractive index of the first scattering unit and the refractive index of the light-emitting center is 0.01-2.0, and the absolute difference between the refractive index of the second scattering unit and the refractive index of the light-emitting center is 0.01-2.0. In this way, the scattering performance of the fluorescent ceramic on fluorescence can be improved, and therefore the light efficiency utilization rate in the light source system is improved.
本申请涉及荧光陶瓷技术领域，具体公开了一种荧光陶瓷及其制备方法、发光装置以及投影装置，该荧光陶瓷至少包括：基质；分布于基质内的发光中心、第一散射单元以及第二散射单元；第一散射单元的折射率大于发光中心的折射率；第二散射单元的折射率小于发光中心的折射率；并且第一散射单元与发光中心的折射率的绝对差值为0.01～2.0，第二散射单元与发光中心的折射率的绝对差值为0.01～2.0。通过上述方式，本申请能够提高荧光陶瓷对荧光的散射性能，从而提高了光源系统中的光效利用率。
