Abstract

The nanocrystalline SrY2O4:Eu3+ was prepared by a poly(vinyl alcohol) (PVA)+glycine-assist combustion method. The results of x-ray diffraction indicate that the resulting SrY2O4:Eu3+ nanocrystals have much broader and less intense peaks compared with those in bulk material. The charge-transfer bands in SrY2O4:Eu3+ nanocrystals shift to higher energies in contrast to those in bulk material. The spectral results revealed that in bulk SrY2O4:Eu3+, the Eu3+ ions occupied three nonequivalent sites, with one at the Sr site: one at the Y(1) site and another at the Y(2) site, while in nanocrystalline SrY2O4:Eu3+, the Eu3+ ions occupied only two nonequivalent sites; one at the Y(1) site and the other at the Y(2) site. Finally, by theoretical calculation and analysis, the analyzed results are in reasonable agreement with our experimental results.
