Abstract
The ZnO-Bi2O3-B2O3 (ZBB) glasses with different concentrations of Bi2O3 have been prepared by a conventional melt quenching technique and investigated the effect of Bi2O3 on the physical, structural and luminescence properties. The density and hardness of glasses are also measured and found to increase with increase of Bi2O3 concentration. The IR studies indicate that these glasses are made up of [BiO3], [BO3], [BO4] and [BO] basic structural units. From optical spectra, the cut-off wavelengths were shifted from 423 nm to 447 nm as the content of Bi2O3 increases from 15 to 30 mol%. The photoluminescence spectra exhibit characteristic peaks at 602 nm corresponding to 3P1 → 1S0 transitions of Bi3+. The decay time for 3P1 level of Bi3+ increases with increase of Bi2O3 concentration. © (2013) Trans Tech Publications, Switzerland.
