Optical and physical properties of lithium doped barium zinc borate glass system

The glass system with composition (70-x)B2O3.20ZnO.10BaO.xLi2O ( x=0,5,10,15,20,25) has been prepared using normal melt quench process. XRD measurement was done to verify the amorphous phase of the system. The glass transition temperature was calculated using DSC and was found to increase initially at low content of Li2O and decreased at high content of Li2O. Various physical properties density, molar volume are also calculated. The optical band gap is measured using UV-VIS spectroscopy.
