摘要

Ce3+-doped scintillating glasses with high light yield and high density are promising candidates for use in electromagnetic calorimeters for particle physics applications. Here, Ce3+-doped glasses with up to 30 moI% Gd2O3 in the system SiO2-B2O3-Al2O3-Gd2O3 have been prepared. Substitutions of Al2O3 by Ga2O3, SiO2 by GeO2 and oxygen by fluorine have been made to increase the density, the resulting effects on optical absorption, luminescence and scintillating properties have been investigated. The glasses made have a high density of 5.0-5.5 x 10(3) kg m(-3). Substitution of fluorine for oxygen resulted in a large increase in the light yield. (C) 2003 Elsevier B.V. All rights reserved.
