Abstract

doped silicate scintillating glass was studied in this paper

we optimized Tb

doped silicate scintillating glass matrix

sensitizer

activator contents

improved the melting temperature

holding time

the atmosphere and so on. According to that fluorides have a better rare earth solubility and a relatively lower phonon energy

the fluoride content in the scintillating glass was adjusted. The energy transfer between Tb

and Gd

was studied according to excitation and emission spectra. The results showed that energy transfer occurs from Gd

and Dy

ions towards Tb

emssion centers as well as the cross relaxation among Tb

ions within a certain concentration range exert tremendous effects on the emission intensity of glass. The Tb

under the certain concentration range contributes to the enhanced Tb

green emission and the weakened Tb

blue emission. Therefore

the luminescent property of Tb

doped silicate scintillating glass has been noticeably improved.
