Abstract: Nano-Y2O3:Eu3+ was prepared with the method of homogeneous precipitation. Controlling theconditions of the reaction, we obtained nano-scale powders with different grain sizes. Compared to ordinarypowders of Y2O3:Eu3+, the XRD peaks of nan-Y2O3:Eu3+ become wide, and 2θ increases. Also, it exitsthe bluc-shift in the X-ray PLS of nano-Y2O3:Eu3+.The wave length and intensity of the peak(5Do7F2)are connected with the grain size of the powders.

Key words: nano-Y2O3:Eu3+, homogeneous precipitation, blue-shift
