Title:
FLUORESCENT CERAMIC AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2019/169868
Kind Code:
A1
Abstract:
A fluorescent ceramic and a preparation method therefor, the fluorescent ceramic comprising a MgO·nAl2O3 matrix (100) and fluorescent particles (200) distributed in the MgO·nAl2O3 matrix; the molar ratio of Al2O3 to MgO in the MgO·nAl2O3matrix is 1: n, wherein 0.9 ≤ n < 1, or, 1 < n ≤ 2. The fluorescent particles are encapsulated at the interior of the MgO·nAl2O3 ceramic by means of secondary sintering.
