摘要：

A solution combustion route for the synthesis of Eu3+-activated M2V2O7 (M = Sr, Ba) and their luminescent properties have been investigated. Structure and luminescent characteristics of Sr2V2O7:Eu3+ and Ba2V2O7:Eu3+ nanophosphors have been studied by x-ray diffraction, scanning electron microscopy, transmission electron microscopy, fluorescence spectrometry and Fourier transform infra-red spectroscopy. The incorporation of Eu3+ activator in these nanoparticles has been checked by luminescence characteristics. These nanoparticles have displayed red color under a UV source which is due to characteristics transition of Eu3+ from D-5(0) -> F-7(2) at 613 nm in both Sr2V2O7:Eu3+ and Ba2V2O7:Eu3+ nanophosphors. In addition, the optimal Eu3+ - doped contents of Sr2(1-x)Eu2xV2O7 and Ba2(1-x)Eu2xV2O7 nanophosphors for both were 4 mol%.
