Novel Tb3+‐activated borogermanate‐tellurite scintillating glasses with a maximum density of 7.15 g/cm3aimed at detection of high‐energy rays were prepared by a melt‐quenching method for the first time. The concentration‐dependent optical properties including transmittance, photoluminescence, luminescence dynamic behaviors, and X‐ray excited luminescence in the as‐prepared Tb3+‐activated borogermanate‐tellurite glasses were studied. The optimal content of Tb2O3in the superdense borogermanate‐tellurite glasses is revealed to be 7 mol% under both 275 nm ultraviolet light and X‐ray excitation. The integral scintillation efficiency of Tb3+‐activated borogermanate‐tellurite scintillating glass is about 33.71% of the standard Bi4Ge3O12(BGO) scintillating crystal.
