Document Type and Number:
WIPO Patent Application WO/2018/233114
Kind Code:
A1
Abstract:
A method for preparing a luminescent ceramic composite material and a luminescent ceramic composite material. The method comprises the following steps: an impregnation and calcination step: impregnating greenware containing a phosphor powder, and an encapsulating material for encapsulating the phosphor powder and an optional sintering aid a in a solution of a precursor of a sintering aid b, and calcinating the impregnated greenware to convert the precursor of the sintering aid b into the sintering aid b; a sintering step: sintering the calcinated green ware to give a luminescent ceramic composite material.
