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 dont move with the increase of the dopant concentration of Sr2+ or Ba2+, but the luminescent intensity increases with increasing Sr2+ or Ba2+ concentration and reaches maximum till x=0.10 (for Sr2+) or x=0.05 (for Ba2+) and then decreases.This may attribute to the effect of charge compensation in the preparation of those phosphors.
