摘要：

Judd-Ofelt analysis of Sin(3+) ions doped in a tellurite glass has been accomplished. Fluorescence and life-time measurements have been carried out using Ar+ laser and excimer laser. Stark splitting has been observed in the upper and lower levels in fluorescence. The life-time of (4)G(5/2) level as a function of Sm3+ concentration has been measured. Concentration quenching and the mechanism responsible for the same have been found. (C) 2002 Elsevier Science B.V. All rights reserved.
