Luminescent Characterization of Nano-Y2O3:Eu3+
纳米Y2O3:Eu3+的荧光特性

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 2 increases. Also, it exitsthe bluc-shift in the X-ray PLS of nano-Y2O3:Eu3 . The wave length and intensity of the peak(5Do - 7 F2)are connected with the grain size of the powders.
