JMS_V3_N4_RP2 Manpreet Kaur Journal on Material Science 2347–615X 3 4 20 27 Phosphate Glass, XRD, FTIR, Band Gap, SEM Phosphate glasses having composition 50P2O5 –30MgO–20Na2O and 50P2O5 –30MgO–15Na2O-5TMO (with TMO(Transition Metal Oxides) as CuO, Fe2O3 and TiO2 ) were prepared using conventional melt quench technique and were characterized for their optical and structural properties. The absence of any sharp peak in the XRD spectra confirmed the amorphous behaviour of prepared glasses. Density of prepared glasses was found in the range of 2.51-2.62 g/cm3 . The FTIR (Fourier Transform Infrared Spectroscopy) spectra of the glasses only showed a variation in the intensity of peaks with doping of different transition elements. The band gap energy and refractive index were calculated from the UVVisible optical absorption spectra in the wavelength range of 200-900 nm. It was found that, the band gap energy was maximum for host glass (3.37 eV) and minimum for CuO doped glass samples (3.21 eV). SEM (Scanning Electron Microscope) morphology also showed the lack of any long range periodicity in the prepared glass samples. January – March 2016 Copyright © 2016 i-manager publications.
