Abstract
Eu3+ doped YVO4 nano phosphors were synthesized by adopting a simple Co-Precipitation Method (CPM). In order to compare and evaluate this method's potentiality, we prepared the same phosphor by using a conventional Solid State Reaction method (SSR). X-Ray Diffraction (XRD) profile confirms the tetragonal nature of Eu3+ doped YVO4 nano phosphors. The efficiency of the prepared phosphors was analyzed by means of its emission spectral profiles. We also observed a rich red emission from the prepared phosphors under a Ultra-Violet (UV) source. Such luminescent powders are expected to be applied as red phosphors in display device applications. In addition, Scanning electron microscopy (SEM), Energy Dispersive X-ray Spectroscopy (EDS), Fourier-Transform IR spectroscopy (FTIR), and Raman Spectrum were also used to characterize the synthesized phosphor. © 2011 The Korean Institute of Metals and Materials and Springer Netherlands.
