在具有任何多极相互作用的随机分布离子的一般情况下分析发光衰减的动力学，并考虑它们之间的能量转移和迁移过程。通过将 Pade 近似应用于激发态群体的 Allinger 和 Blumen 表达式，获得了一个可以轻松拟合实验数据的简单表达式。该表达式可以被认为是偶极-偶极 Yokota-Tanimoto 方程的推广。另一方面，针对不同的 Tb3+ 浓度，测量了氟锌酸盐玻璃中 Tb3+ 离子 5D3 能级的衰减曲线。在所提出的表达式的框架内分析结果。
The dynamics of luminescence decay is analyzed within the general scenario of randomly distributed ions with whatever multipole interaction, taking into account energy transfer and migration processes among them. By applying Pade approximants to the Allinger and Blumen expression for the excited state population, a simple expression has been obtained which can be easily fitted to experimental data. This expression can be considered a generalization of the dipole–dipole Yokota–Tanimoto equation. On the other hand, the decay curves from the 5D3 level of the Tb3+ ions in fluorozincate glasses have been measured for different Tb3+ concentrations. The results are analyzed in the framework of the proposed expression.
