摘要：

The paper presents the synthesis and spectroscopic properties of 46PbO:53P(2)O(5):Ln(2)O(3) glasses, where Ln = Sm or 0.1Sm + 0.9Gd. The glasses show intense luminescence dominated by the orange (4)G(5/2) -> H-6(7/2) transition. The luminescence branching ratios and quantum yields have been computed using the Judd-Ofelt analysis of relevant absorption spectra and the observed luminescence lifetimes; the maximum found quantum yield was 69%. The lifetimes and the quantum yields depended on the time of heating the samples at high temperature and on the samarium concentration. (c) 2007 Elsevier B.V. All rights reserved.
