摘要：
The present work reports the effect of concentration on photoluminescence properties of Sm3+ ions doped lead tungstate tellurite (LTTSm) glasses by using the absorption, emission and decay measurements. The Judd-Ofelt theory has been used to evaluate the three Judd-Ofelt intensity parameters (ohm(2,4,6)) and calculated oscillator strengths (f(c)). LTTSm glasses exhibited intense reddish-orange emission when excited with 477nm wavelength. Concentration quenching has been noticed beyond 1.0 mol% of Sm3+ ion concentration. The decay curves of (4)G(5/2) level exhibited single exponential behavior for all the concentrations and the measured lifetimes are found to depend strongly on Sm3+ concentration. From the emission characteristic parameters of (4)G(5/2) level, it is concluded that the LTTSm glasses could be useful for photonic devices like visible lasers, fluorescent display devices and optical amplifiers.
