The studies of energy transfer between Sm3+ ions in lead sodium telluroborate glasses using Inokuti-Hirayama model
Keyword(s):
Lead sodium telluroborate (LSTB) glasses doped with different concentrations of Sm3+ ions were prepared by melting method. The excitation, emission spectra and lifetimes of LSTB:Sm3+ have been investigated. The quenching of luminescence intensity happens after 0.75 mol% concentration of Sm3+ ions. The non-exponential decay curves are fitted to the Inokuti and Hirayama model to give the energy transfer parameters between Sm3+ ions. The dominant interaction mechanism for energy transfer process is dipole–dipole interaction. The energy transfer probability (WDA) increases whereas lifetime (τexp) decreases with the increase of Sm3+ concentration in glass.
