Composite fluorescent ceramic, preparation method and light emitting device thereof

Abstract

The disclosure discloses a composite fluorescent ceramic, a preparation method of the composite fluorescent ceramic and a light emitting device related to the technical field of optical components. The device includes a luminescent phase, a matrix phase and pores, the luminescent phase includes multiple luminescent crystal grains bonded together, the matrix phase includes multiple matrix crystal grains bonded together, the matrix phase and the luminescent phase are interspersed with each other and distributed in a composite fluorescent ceramic, at least part of pores are distributed in the luminescent phase, at least part of pores are distributed in the matrix phase, and at least part of pores are distributed between the luminescent phase and a Al2O3 matrix phase. The composite fluorescent ceramic may have high scattering performance.
