Synthesis of Ultrafine GSAG:Ce Phosphor by Solution Combustion
Ultrafine cerium-doped GSAG phosphor powders are prepared by a solution combustion process using glycine and urea as fuel. Single-phase cubic GSAG:Ce crystalline powder is obtained by calcining the as-synthesized amorphous materials at 800oC and no intermediate phase is observed. Transmission electronic microscope morphology shows that the resultant GSAG:Ce powders have uniform size and good homogeneity. The photoluminescence spectra of Ce3+ substituted for Ce3+ in GSAG has been measured on samples calcined at 1000oC.
