Laser spectroscopy of Nd3+ ions in glasses with the 0.8CaSiO3-0.2Ca3(PO4)2 eutectic composition
چکیده انگلیسی
In this work we report the study of site-selective laser spectroscopy of Nd3+ ions in glasses with the 0.8CaSiO3-0.2Ca3(PO4)2 eutectic composition together with a dynamic study of energy transfer among Nd3+ ions by using time-resolved fluorescence line narrowing (TRFLN) spectroscopy. The spectral features of the time-resolved fluorescence line narrowed 4F3/2→4I9/2 emission spectra obtained under resonant excitation reveal the existence of spectral migration of excitation among the Nd3+ ions. The analysis of the time evolution of the 4F3/2→4I9/2 narrowed emission shows that the electronic mechanism responsible for the ion-ion interaction can be identified as a dipole-dipole energy transfer process.
