Changes in the position and the intensity parameters of the transitions are closely related to structural changes in the glass network. A Judd-Ofelt scheme was used to estimate the intensity parameters Omega(lambda) and radiative properties for Sm3+ in the glass. The behaviour of Omega(2) and Omega(6) parameters suggested a decrease in the asymmetry degree of the local ligand field at Sm3+ sites and an increase in the covalency of Sm-O bond, respectively, This hypothesis was verified by analysing the structural role of Sm2O3 through Raman and infrared spectroscopy measurements.
