Abstract
Multicomponent borosilicate glasses containing 0.5–5 wt % of Sm2O3 are synthesized via high-temperature melting in air. Samples are irradiated in a van de Graaff accelerator at 2.5 MeV. The kinetics of the decay of luminescence of Sm3+ and Sm2+ ions is analyzed, along with the evolution of the lifetimes of the excited states of these ions, depending on the concentration of Sm2O3. It is found that the curves for the decay of luminescence can be approximated by a bi-exponential function even for low concentrations of samarium. The results correspond to different structural environments for Sm3+ and Sm2+ ions.
