The Studies of Energy Transfer between Sm3+ ions in Lead Sodium Telluroborate Glasses Using Inokuti-Hirayama Model

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. T...
