摘要：

Scintillation glasses for hadron calorimeter need high density and excellent luminescent properties. Eu3+-doped TeO2-GeO2-BaO scintillation glasses with the nominal composition of xTeO2-(60-x)GeO2-39BaO-1Eu2O3 (x = 20, 25, 30, 35, 40, 45, and 50) were prepared by melt-quenching method. The structural information induced by various TeO2/GeO2 ratios were discussed by means of density, FTIR spectra and transmittance spectra, together with the asymmetric ratios of Eu3+ ions and Judd-Ofelt analysis. The luminescent properties of Eu3+-doped TeO2- GeO2-BaO scintillation glasses are described byphotoluminescence (PL) and X-ray excited luminescence (XEL) spectra. The results suggest that both PL and XEL intensity of Eu3+-doped TeO2-GeO2-BaO scintillation glasses are observed to drops clearly with an increase in x values, whereas the glass density shows a slight increase. Therefore, a balance should be search for the possible scintillation application between the luminescent effi-ciency and the strict density requirement.
