Tb3+掺杂高密度锗酸盐闪烁玻璃的发光性质
Luminescence Properties of Tb3+ Doped High Density Germanate Scintillating Glasses
摘要
Abstract
Tb3+ doped high density germanate glasses were prepared by melt-quenching method.Their physical and luminescent properties were characterized by transmittance spectra,density,photoluminescence,fluorescence lifetimes and X-ray excited luminescence spectra.The transmittance spectra show the glasses have good transmittance in the visible spectrum region.The high Lu2O3 and Gd2O3 contents ensure germanate glass density approach to 6.4 g/cm3.The glasses show intense green emissions under 377 nm light and X-ray excitations.The lifetimes of 544 nm emission are in the range from 1.325 ms to 1.836 ms.The results indicate that Tb3 + doped high density germanate glass is a scintillating material candidate used in X-ray detector for slow event.关键词
