Abstract
In this work we report the study of site-selective laser spectroscopy of Nd 3+ ions in glasses with the 0.8CaSiO 3–0.2Ca 3(PO 4) 2 eutectic composition together with a dynamic study of energy transfer among Nd 3+ ions by using time-resolved fluorescence line narrowing (TRFLN) spectroscopy. The spectral features of the time-resolved fluorescence line narrowed 4 F 3 / 2 → 4 I 9 / 2 emission spectra obtained under resonant excitation reveal the existence of spectral migration of excitation among the Nd 3+ ions. The analysis of the time evolution of the 4 F 3 / 2 → 4 I 9 / 2 narrowed emission shows that the electronic mechanism responsible for the ion–ion interaction can be identified as a dipole–dipole energy transfer process.
