Abstract

This study reports on physical and optical properties of Dy3+ doped bismuth borate glass. The glasses containing Dy3+ in (70-x)B2O3:30Bi2O3:xDy2O3 (where x = 0.0-2.5 mol%) have been prepared by melt-quenching method. In order to understand the role of Dy2O3 in these glasses, the density, molar volume and optical spectra were investigated. The results show that molar volume of the glasses increase with the increasing of Dy2O3 concentration and consequently generating more non-bridging oxygen (NBOs) into glass matrix. The absorption spectra of Dy3+ doped in bismuth borate glass correspond with several bands, which are assigned from the ground state, 6H15/2 to 6F3/2(761 nm), 6F5/2(806 nm), 6F7/2(907 nm), (6H7/2, 6F9/2)(1099 nm), (6F11/2, 6H9/2) (1283 nm) and 6H11/2(1695 nm). Moreover, the optical basicities were also theoretically determined.
