The interaction of stimulating radiation with matter produces defects which can be divided into two groups: 1. electronic defects, 2. ionic defects. The formation of defects is essentially determined by electronic processes and elastic impacts. The supply of energy in the form of heat makes possible a thermal stimulation the probability of which is characterized by a Boltzmann factor. Whereas the classical explications are based on thermodynamic or statistical considerations, the quantum mechanical calculation relates to non-radiative transitions from traps. For the radiating recombination a selective rule is valid which guarantees the conservation of energy and impulse. The phenomenological description of thermoluminescence makes use of the kinetic processes in the non-stationary case and allows in simple models the determination of trap parameters, such as activation energy or pre-exponential factor. The simple models can be extended by introducing thermally separated trap levels. If the kinetic balance equations are solved exactly with the aid of an analogic computer, the simulated Glow curves show a good correspondence with experimental curves.
刺激辐射与物质的相互作用会产生缺陷,这些缺陷可分为两类:1. 电子缺陷,2. 离子缺陷。缺陷的形成本质上由电子过程和弹性碰撞决定。以热的形式提供能量使得热刺激成为可能,其概率由玻尔兹曼因子表征。虽然经典解释基于热力学或统计考虑,但量子力学计算涉及从陷阱的非辐射跃迁。对于辐射复合,一个选择定则是有效的,它保证了能量和动量的守恒。热释光的唯象描述利用了非稳态情况下的动力学过程,并在简单模型中允许确定陷阱参数,如激活能或指数前因子。通过引入热分离的陷阱能级,可以扩展简单模型。如果借助模拟计算机精确求解动力学平衡方程,模拟的辉光曲线与实验曲线显示出良好的对应关系。
