Effect of ZnO on physical and optical properties of bismuth borate glasses |
| 초록 |
This paper presents results and observations obtained from a study of the effects of zinc oxide on the optical properties of B2O3-Bi2O3-ZnO glasses. In this study, we have prepared glasses with composition 2xZnO-(50-x)[B2O3 ∙ Bi2O3], (x = 0, 5, 10, 15) and have analyzed physical, thermal and optical properties of glass. Systematic variation in density and molar volume in these glasses indicates the effect of ZnO on the glass structure. Differential thermal analysis (DTA) studies showed that the glass transition temperature (Tg) decreases from 423℃ to 390℃ as the content of ZnO increases. The values of optical band gap and theoretical optical basicity are also investigated. |
