The thermal-lens (TL) method was applied to a new phosphate glass doped with Nd 3+ to determine fluorescence quantum efficiency (η) and thermal properties such as: thermal diffusivity, thermal conductivity and the temperature coefficient of optical length change. Studies were performed as a function of Nd 3+ concentration (0.5-3 × 10 20 ions/cm 3). In addition, fluorescence quenching was studied by measuring the concentration dependence of fluorescence lifetime. The TL and fluorescence lifetime results are in good agreement and corroborate the theory for energy transfer involving a pair of ions in which cross-relaxation (CR) is the dominant process. © 2012 Elsevier B.V.
