Abstract

Ho3+ doped zinc bismuth borate glasses of the composition 10ZnO: 30Bi2O3: (60-x)B2O3: xHo2O3 (where x = 0. 0, 0. 2, 0. 4, 0. 6, 0. 8 and 1. 0 mol%) were fabricated by conventional melt quenching technique. In order to understand the role of Ho2O3 in these glasses, the density, molar volume and optical spectra were investigated. The molar volume decreases with an increase in Ho2O3 content, which is attributed to the structure becomes more compacted. The absorption spectra of Ho3+ doped in zinc bismuth borate glass correspond to several bands, which are assigned from the ground state, 5I8 to 5G5 (420 nm), 5G6 + 5F1 (451 nm), 5F2 + 5F4 (538 nm), 5F5 (643 nm) and 5I5 (1152 nm). Moreover, the optical basicities were also theoretically determined. ฉ (2014) Trans Tech Publications, Switzerland.
