Abstract: Ultrafine powders of Y3Al5O12(YAG):Ce3+ were prepared by the ployacrylamide gel, and the spectra characterization of the powders was studicd. Compared with coprecipitation process, YAG phase can be got at lower temperature (900℃) by the polyacrylamide gel. The blue-shift in the spectra of ultrafine YAG:Ce3+ powders was found.

Key words: polyacrylamide gel, YAG:Ce3+, ultrafine powders, blue-shift
