摘要：

YVO4:Eu3+ nanocomposites have been synthesized by means of a modified co-precipitation method (CP-CNT). Multi walled carbon nanotubes (MWCNT's) have been employed in the synthesis of the YVO4:Eu3+ nanocomposites to enhance its photoluminescence efficiency. The prepared nanocomposites were thoroughly characterized using the characterization techniques namely XRD, SEM, FT1R and Raman scattering. To evaluate the potentiality of the prepared nanocomposites, the same phosphor has also been prepared by using co-precipitation (CP) method without employing multi walled carbon nanotubes and also by means of conventional solid state reaction method (SSR). The photoluminescence spectra of YVO4:Eu3+ nanocomposites have shown stronger red emission at 619 nm (D-5(0) -> F-7(2)) for both the excitation wavelengths (254 and 393 nm) than the other two prepared samples. The effect of MWCNT's on photoluminescent properties of the YVO4:Eu3+ nanocomposites is also explained. (C) 2011 Elsevier Ltd. All rights reserved.
