摘要

Tellurium based glasses containing WO3, B2O3 and K2O are investigated through density, glass transition temperature and optical properties. The density and glass transition temperature of the present gasses varies with K2O mole%. From the optical absorption studies, the values of direct optical band gap, indirect optical band gap energy (E_0) and Urbachenergy(ΔE) have been evaluated. The values of E_0 and ΔE vary linearly with K2O mole%. The electronic polarizability of oxide ions, optical basicity and the Yamashita- Kurosawa's interaction parameter have been examined to check the correlation among them and bond character. Based on good correlation among electronicpolarizability of oxide ions, optical basicity and the Yamashita- Kurosawa's interaction parameter, the present K_2O-TeO_2-WO_3-B_(2O3) glasses were classified as normal ionic (basic) oxides.
