Optical investigation of erbium doped lead tellurite glass: Judd-Ofelt Analysis

Understanding the absorbance characteristics in topically important rare earth doped tellurite is the issue. The characterizations of optical properties of these glasses are very important for the optimization and nanophotonic applications. The superior nonlinear optical properties, low phonon cutoff, and high quantum efficiency amongst many other characteristics make them promising for potential applications. All of these considerations comprise a powerful control feature for the fabrication of rare-earth doped tellurite glass. In the present work, the absorbance effects of Er3+ doped tellurite glasses synthesized by melt-quenching technique have been investigated. The measured absorption spectra were analysed by Judd-Ofelt. Our findings may provide some useful information towards the development of functional glasses. (C) 2015 Published by Elsevier Ltd.
