Abstract:
In this paper,a series of(Y0.98-xSrx)3Al5O12:Ce0.06 or(Y0.98-xBax)3Al5O12:Ce0.06 phosphors were prepared using moderate high temperature solid-state reaction.The products were analyzed by XRD,the results show that all systems have cubic garnet structures when doping concentration is less than 0.10 for Sr2 + ions or 0.05 for Ba2 + ions.The products were characterized by luminescence spectra,the results indicate that the emission spectra peak don't move with the increase of the dopant concentration of Sr2 + o...
Keywords:WLED  high temperature solid-state reaction  YAG:Ce3 phosphor
