Eu3+-activated heavy scintillating glasses

Abstract Eu 3+ -activated scintillating glasses with molar compositions of 35SiO 2 –15B 2 O 3 –30Ln 2 O 3 –20AlF 3 (Ln = Y, La, Gd, Lu) have been prepared. The effects of Ln 3+ ions on the density, transmission, photoluminescence and radioluminescence have been studied. The glasses have high density, ranging from 4.0 to 6.1 g/cm 3 in the order of Y
