摘要

摘要根据对已发表数据的分析，我们提出了一种观点，即在剂量测定中使用的硼酸盐荧光粉中，会发生空穴从陷阱到重组中心的级联双光子转移。在之前描述的动力学模型的基础上，补充了处于瞬态的空穴对第二个光子的吸收。结论是，如果在双光子机制下进行读出，则刺激光通量的强度应准确稳定，因为在这种情况下，光刺激辉光曲线的最大振幅与光通量的强度有着复杂的关系。

Two-Photon Optical Stimulation for Readout of Radiation Detectors

Based on an analysis of published data, we formulate an idea that a cascade two-photon transfer of holes from traps to recombination centers occurs in borate phosphors used in dosimetry. The previously described kinetic model is supplemented with the absorption of a second photon by a hole in a metastable state. It is concluded that the intensity of the stimulating light flux should be accurately stabilized if readout occurs in the two-photon regime, since in this case the maximum amplitude of the optically stimulated glow curve has a complex dependence on the intensity of the light flux.
