title: Spectroscopic investigations of Er3+ :CdO-Bi2 O3-B2O3 glasses.
abstract: This article reports on the optical properties of Er3+ ions doped CdO-Bi2O3-B2O3 (CdBiB) glasses. The materials were characterized by optical absorption and emission spectra. By using Judd-Ofelt theory, the intensity parameters Ω(λ) (λ = 2, 4, 6) and also oscillatory strengths were calculated from the absorption spectra. The results were used to compute the radiative properties of Er3+ :CdBiB glasses. The concentration quenching and energy transfer from Yb3+ -Er3+ were explained. The stimulated emission cross-section, full width at half maximum (FWHM) and FWHM × σpE values are also calculated for all the Er3+ CdBiB glasses.
