中文摘要：
摘要用高温熔融法制备了Ce3＋／Tb3＋掺杂的高钆镥氟氧化物闪烁玻璃样品，测试分析了其密度、透射光谱、激发与发射光谱、X射线激发发射光谱及衰减曲线等。制备的闪烁玻璃具有高的闪烁光输出，密度大于5．8g／cm2，闪烁玻璃中Ce3＋离子的引入有利于促进Tb3＋离子发光。用Inokuti—Hirayama（I-H）理论模型分析了铈／铽掺杂高钆镥闪烁玻璃的能量传递机理，分析结果表明Ce3＋→Tb3＋的能量传递形式是无辐射共振能量传递。通过拟合数据和理论公式计算出了两者之间能量传递的速率和效率，其能量传递速率PSA和Tb3＋离子浓度的平方成正比关系，而能量传递效率η随Tb3＋离子浓度增加而升高。
英文摘要：
The Ce3＋/Tb3＋ doped oxyfluoride glasses with high Gd[（1-x）Lux]2O3 concentration are prepared by high temperature melting method. The densities, transmission spectra, excitation spectra, emission spectra under ultraviolet （UV） and X-ray excitations and decay curves of Ce3＋ ions are measured and analyzed. The scintillating glasses have excellent performance of high light output. The densities of the glasses are greater than 5.8 g/cm3 . The Ce3＋ ions can sensitize the luminescence of Tb3＋ ions. The energy transfer mechanisms of the Ce3＋/Tb3＋ doped scintillating glasses are analyzed by the I-H theory model. The energy transfer rate and energy transfer efficiency between Ce3＋ and Tb3＋ ions are calculated by the fitting data and theoretical formula. The results indicate that the energy transfer mechanism is non-radiative energy transfer, the energy transfer rate is proportional to the square of the Tb3＋ ions concentration, and energy transfer efficiency increases with the concentration of Tb3＋ ions.
