| Summary: | Title screen Transparent ABS-BGP (Al2O3-B2O3-SiO2-BaCO3-Gd2O3-P2O5) glasses doped with different level of Tb3+ concentrations (from 0 to 12 mol.%) were synthesized by the high-temperature melting method. The luminescent and energy transfer properties were investigated by transmittance, photoluminescence, cathodoluminescence (CL) and X-ray excited luminescence spectra. The optimal concentration of Tb3+ ions in ABS-BGP glasses excited by both ultraviolet light, electron beam, and X-ray excitation was also determined. The decay time of 543 nm main emission band of Tb3+ doped glasses decrease in the range from 1.66 ± 0.005 to 1.18 ± 0.005 ms with increasing of Tb3+ions. The energy transfer mechanism was discussed, and the corresponding critical distances for Tb3+-Tb3+ ion pairs were calculated. The integral scintillation efficiency of the 10 mol% Tb3+-doped ABS-BGP glass sample reach 63.9% of the Bi4Ge3O12 (BGO) standard crystal.
