Influence of Dy3+ Ion on Physical Properties and Absorption Studies of Zirconium Based Alkali Borate Glasses

Abstract

Influence of Dy3+ ion on physical and absorption studies of zirconium based alkali borate glasses have been prepared using muffle furnace by conventional melt quench method. Samples were analyzed using certain measurements like XRD and UV-Vis. Physical parameters like density, molar volume were calculated. XRD spectra confirm the amorphous nature of all samples as there is no sharp peaks. Uv-Visible absorption studies were carried out and by utilizing Tauc's equation direct and indirect band gap, Urbach energy was estimated. Energy band gap values are tabulated and discussed in detail for the better understanding
