基于热释光事件发生经历一个复杂的多阶段的过程和电离辐射与介质相互作用事件的随机性,并考虑到热释光材料中掺入的杂质所决定的电子陷阱和空穴陷阱的空间分布、电离辐射在介质中能量沉积的空间分布以及与加热温度相关的载流子漂移均直接影响热释光事件的产生,从统计学泊松分布导出一个一次作用和二次作用复合的热释光剂量响应函数,描述热释光剂量响应。响应函数中的两个特征参量,即一次作用因子R和特征剂量D_0,可表征热释光剂量响应的非线性特性和灵敏度。对热释光剂量响应的非线性与材料中所掺入的杂质成分和含量的关系,以及对入射粒子的传能线密度和热释光峰温等相关的一系列实验结果也作了较好的解释。
The spatial distribution of electron traps and hole traps that are governed by the process of a complex, multi-stage process and the interaction of ionizing radiation with the medium, taking into account the impurities incorporated in the thermoluminescent material, , The spatial distribution of energy deposition of ionizing radiation in the medium and the drift of carriers related to the heating temperature all directly affect the generation of thermo-luminescence events. A thermodynamic luminescence with one-time and two-action recombination is derived from the statistical Poisson distribution Dose response function, describing the thermoluminescent dose response. The two characteristic parameters of the response function, namely, the first-order action factor R and the characteristic dose D_0, can characterize the nonlinear characteristic and sensitivity of the thermoluminescence dose response. The relationship between the nonlinear response of TLR and the composition and content of impurities incorporated in the material, as well as a series of experimental results related to the energy transfer linear density and the TL peak temperature of the incident particles are also better explanation of.
