玻璃中X射线诱导闪烁的效率大致取决于玻璃的有效原子序数Zeff和光致发光量子效率Qeff，这是寻找高性能荧光粉的有用工具。在这里，我们证明了从主机到激活剂的能量转移也是一个重要因素，为实现高闪烁效率的Ce掺杂氧化物玻璃。与Ce3+和Ce4+物种的共存分数的玻璃的闪烁强度被发现是高于纯Ce3+的含玻璃具有较低的Zeff值。每个样品的总衰减值表明闪烁强度与总衰减和Qeff的乘积之间存在非线性相关性。所得结果说明理解电离辐射引起的发光的困难，包括能量吸收和随后的能量转移。我们的研究结果可能为通过调整局部结构来合成新型的手性化合物提供一种新的途径。
The efficiency of X-ray-induced scintillation in glasses roughly depends on both the effective atomic number Zeff and the photoluminescence quantum efficiency Qeff of glass, which are useful tools for searching high-performance phosphors. Here, we demonstrate that the energy transfer from host to activators is also an important factor for attaining high scintillation efficiency in Ce-doped oxide glasses. The scintillation intensity of glasses with coexisting fractions of Ce3+ and Ce4+ species is found to be higher than that of a pure-Ce3+-containing glass with a lower Zeff value. Values of total attenuation of each sample indicate that there is a non-linear correlation between the scintillation intensity and the product of total attenuation and Qeff. The obtained results illustrate the difficulty in understanding the luminescence induced by ionizing radiation, including the energy absorption and subsequent energy transfer. Our findings may provide a new approach for synthesizing novel scintillators by tailoring the local structure.
