摘要：

In this paper we report on optical and spectroscopic properties of an innovative erbium-doped modified silicate Baccarat glass of molar composition: 77.29SiO(2):11.86K(2)O:10.37PbO:0.48Sb(2)O(3). Two different sets of samples were produced, containing 0.2 and 0.5 mol% Er3+ ions, respectively. Optical and spectroscopic assessment of these glasses was performed by absorption, photoluminescence, and refractive index measurements. The quantum efficiency was estimated comparing measured and radiative lifetime of the I-4(13/2) metastable state of the Er3+, the latter obtained by Judd-Ofelt analysis. (c) 2006 Elsevier B.V.
