Synthesis and Luminescent Properties of Ce~(3+)-Activated SrGa_2O_4 and Sr(Ga-Al)_2O-4

摘要

Ce~(3+) -doped SrGa_2O_4 was synthesized by citrate-gel with citric acid as chelate agent and sintered in a slightly reduced atmosphere of hydrogen and nitrogen mixture, It was found that the phosphor synthesized by citrate-gel can be sintered at relatively lower temperature. The luminescent properties of Ce~(3+)-activated SrGa_2O_4 and the complex Sr(Ga-Al)_2O_4 were studied.
