Abstract

The modifications induced in YVO4 nanocrystals by the thermal treatments are observed and analyzed using Er3+ as a probe. These modifications are discussed in the frame of the Judd-Ofelt theory. The results are compared with the previous ones, obtained with Eu3+ as a probe..

Keywords

YVO4, Er3+, Nanocrystals, Luminescence, Judd-Ofelt.
