【摘要】 采用固相反应法制备了Bi³⁺、Eu³⁺、Tb³⁺掺杂的Lu₃TaO₇。测量了样品的X射线衍射谱、激发和发射光谱及荧光衰减曲线。三种离子掺杂的Lu₃TaO₇均呈现出强的荧光发射,其中Bi³⁺具有峰位在431 nm处的一强发射宽带,衰减寿命为16.8μs,Eu³⁺、Tb³⁺则表现出稀土离子的特征锐发射峰,衰减寿命分别为1.26ms和1.20ms。因此,它们均是具有潜在应用前景的重闪烁体材料。更多还原

【Abstract】 Bi³⁺,Eu³⁺,Tb³⁺ doped Lu₃TaO₇ were synthesized by solid-state reaction method.The powders were characterized by XRD patterns,excitation,emission spectra and decay curves.All of Lu₃TaO₇doped by the three kinds of ions show the considerable strong luminescence,Bi3+ presents a broad emission band peaking at 431 nm and the decay time is 16.8 μs,Eu³⁺,Tb³⁺ show the typical sharp emission peaks of rare earth ions and the decay times are 1.26 ms and 1.20 ms,respectively.So they can be applied as potential high-density scintillators.更多还原
