Effect of microwave time on the structural and luminescence properties of YAG:Ce prepared by microwave solution combustion (MSC) synthesis

Autor: Way Foong Lim, Khai Shenn Lau, Hock Jin Quah, Zainuriah Hassan, Sabah M. Mohammad

Publikováno v: Optik. 212:164437

Microwave solution combustion (MSC) synthesis is an attractive synthesis method to produce luminescent phosphor materials. The combustion reaction triggered by the interaction between microwave radiation and reducing agents (fuels) can produce high q
