Luminescence properties of Tb3+-doped oxyfluoride scintillating glasses
MetadataShow full item record
Transparent oxyfluoride glasses doped with Tb3+ were prepared by melt quenching method. The transmittance spectra show the glasses have good transmittance in the visible spectrum region. The emission spectra under 376 nm light and X-ray excitations were recorded. Tb3+ doped oxyfluoride glasses show intense green emissions under both excitations. The optimum concentrations of Tb3+ ion are around 8 mol% and around 10 mol% under 376 nm light excitation and X-ray excitation, respectively. The lifetimes of 541 nm emission of oxyfluoride glasses doped with Tb3+ are in the range from 2.65 ms to 3.02 ms. The results indicate that Tb3+-doped oxyfluoride glasses could be an X-ray scintillating material suitable to X-ray detection for slow event. © 2013 Elsevier B.V.
