| Abstract: | This paper reports on the spectral analysis of novel Lithium Zinc Vanadate (LiZnVO4) phosphor prepared by a solid state reaction method. Emission spectrum of LiZnVO4 has shown a bright green emission at 533 nm with λexci = 359 nm. A bright green color emission has also been noticed directly from this phosphor under an UV source. For this luminescent phosphor, X-ray diffraction (XRD), Scanning electron microscopy (SEM), Energy dispersive X-ray spectroscopy (EDS), Fourier-transform IR spectroscopy (FTIR), Raman Spectrum, Comprehensive Differential Thermo gravimetric Analysis (TG–DTA) have also been carried out. |
