EFFECTS OF PARTICLE SIZE ON THE LUMINESCENCE OF YVO4:Eu NANOCRYSTALS

YVO4:Eu nanocrystals synthesized by direct precipitation reaction. The morphologic transformation of the nanocrystals as the results of thermal treatments were analyzed using optical spectroscopy. A red shift of the fluorescence lines with the increase of the crystallite size was observed. The kinetics of the 5 D0 level of Eu 3+ is also analyzed.
