摘　　要：The glass-forming regions of tellurium-gadolinium-tungsten ternary system prepared at 1000℃for 60 min were firstly determined.To improve density,the full replacement of lutetium for gadolinium to form Tb^(3+)-activated tellurium-lutetium-tungsten glasses with the composition of 64 TeO_(2)-20 WO_(3)-(16-y)Lu_(2)O_(3)-yTb_(2)O_(3)were designed for scintillation application.The concentration-dependent optical properties of Tb^(3+)-activated tellurium-lutetium-tungsten glasses were fully investigated by transmittance,excitation and emission spectra,together with the luminescence decay curves.The energy transfer mechanism was discussed according to Huang’s rule.The optimized 4 mol%Tb_(2)O_(3)activated tellurium-lutetium-tungsten glasses with the density of 6.49 g/cm^(3)and the lifetime of 0.551 ms are developing to be suitable for the potential detection of slow events in the future work.
