报道了一种新的基于Yb ~（3+）电荷转移发光的掺Yb ~（3+）超快发光材料。采用烧结法制备了Yb 3+掺杂的Y2 O3、Sc2 O3、Lu 2 O3和Yb 2 O3透明陶瓷。在γ射线和X射线辐照下，它们的脉冲高度谱中有一个可探测到的光吸收峰，闪烁衰减时间约为1 ns。对于第一次，Yb 3+掺杂的氧化物材料在室温下的脉冲高度测量中显示出可检测的闪烁，具有超快闪烁衰减。
We report a new discovery of Yb3+-doped ultrafast scintillators based on the Yb3+ charge transfer luminescence. Transparent ceramic Yb3+-doped Y2O3, Sc2O3, Lu2O3, and Yb2O3 were prepared by sintering. When irradiated by γ- and X-rays, they showed a well detectable photoabsorption peak in the pulse height spectra and ultrafast scintillation decay dominated by the decay time of about 1 ns. For the first time, the Yb3+-doped oxide materials show detectable scintillation in the pulse height measurement at room temperature with ultrafast scintillation decay.
