Abstract
A multiphase fluorescent ceramic and a preparation method therefor. Spinel is provided in a multiphase fluorescent ceramic including an alumina matrix and fluorescent particles, the spinel is distributed between alumina grain boundaries, and the exciting light irradiated into the multiphase fluorescent ceramic can be scattered, thereby facilitating further improvement in the luminous efficiency of the multiphase fluorescent ceramic.
