Abstract

Er3+ ions doped lead borotellurite glasses were prepared by melt quenching technique and their structural and spectroscopic behaviors were studied through recording FTIR, UV–Vis–NIR absorption and photoluminescence measurements. Through the absorption spectra the bonding parameters (d) and Judd–Ofelt intensity parameters Ωλ (λ = 2, 4 and 6) has been evaluated. From the JO intensity parameters the radiative properties such as transition probability (A), stimulated emission cross section (σe), radiative life time (τcal) and branching ratios (βR) of the prepared glasses were determined and their results were discussed and reported. The obtained higher values of A, σe, FWHM and ∆G for the LTB0.5E glass suggest its feasibility for the development of laser and optical amplifier devices.
