- Abstract
Herein, we demonstrate the transition metal oxides (CuO, TiO2) induced structural, optical, luminescence and elastic characteristics of (60 − x)B2O3 + 20K2O + 10ZnO + 10ZnF2 + xTMO glasses produced via the melt-quenching process. The prepared glass samples were comprehensively studied through various characterization techniques systematically using XRD, FTIR, and UV–Visible spectroscopic techniques. In addition, the elastic properties were evaluated using the Makishima–Mackenzie theoretical model. It was found from the structural studies by XRD show that the glass samples exhibit amorphous characteristics even after doping with TMOs. There is no significant variation in the physical parameters upon adding TMOs, indicating the structural stability of the prepared glasses and the occurrence of non-bridging oxygens in the glass matrix. while FTIR analysis revealed the predominance of borate groups for all the prepared samples. UV–Visible absorption spectral studies demonstrate the presence of prominent electronic transitions originated by incorporating dopant (CuO) in the case of BCu glass samples. In contrast, other glasses (B and BTi) show no signatures. Further, the estimated indirect energy band gap and Urbach energy values were higher than the base (host) glass. The elastic properties such as estimated elastic moduli describe the elastic behaviour of the prepared glasses. Among all the glasses, BCu glass stands out for its exceptional optical and elastic qualities.
