Abstract
Phosphate glasses of chemical composition xCuO–(24-x)K2O–48P2O5–28ZnO; where x = 0, 2, 4, 6, 8 and 10 molar ratios, have been prepared using the melt quenching technique. Density, molar volume, oxygen packing density and oxygen molar volume have been calculated. Water durability is determined from the measurement of the dissolution rate in deionized water. The dissolution rate is found to decrease with increasing CuO, indicating the improvement of water durability. FTIR spectroscopy of all glass samples has been investigated in the wavenumber range 400–2000 cm−1. Analysis of FTIR spectra confirms the structural role of CuO as a network modifier. Optical spectroscopy of these phosphate glasses has been measured over the wavelength range of 190–2000 nm. By calculating the optical bandgap, it is found that Eg decrease with increasing CuO indicating the creation of non-bridging oxygens.
