Effect of Sn on Physical and Optical Properties of Lithium Zinc Borate Glasses

Abstract

Abstract 22.5 Li2O3-(20-x) ZnO-57.5B2O3 – xSnCl2 (x = 0, 0.5. 1) glasses were synthesized using the conventional melt quench technique. Glass composition with larger concentration of lithium oxide exhibits excellent transport properties. Introducing intermediate element like zinc into the matrix will lead towards slight modification in structure by not varying much in its intrinsic properties. Thus, incorporation of Sn as dopant into the matrix has tailored the physical and optical properties of glasses. In this study, it is interesting to note that, the density of the glass has reduced for 0.5 mol % SnCl2 in the matrix and on the contrary, the density of glass was found to be increased for the SnCl2 with 1 mol % concentration. It indicates that, there could be a possibility of slight modification in the structure of glasses which eventually leads towards tuning of the optical bandgap due to existence of Sn.
