| Abstract | ||||
| Copper doped phosphate glass has been prepared by conventional melt quenching technique. The composition of the prepared system is 42 P2O5- 39ZnO- 4CaO- (15-x) Na2O- xCuO, where (x= 2, 4, 6, 8 and 10 mol %). The amorphous nature of the glassy system have been checked by X-ray diffraction (XRD). The density ρ has been measured by Archimedes method, using a toluene as the immersing liqued . The molar volume (Mv) has been calculated. It is observed that, the density of the prepared glasses increases by increasing copper oxide content and the molar volume Mv exhibit the same trend. The optical absorption spectra were measured in visible and near IR spectral regions. The data reveal that, such system exhibits band pass filtering effect. The hight and weidth of absorption band were found to be copper concentration dependent. | ||||
