Approximate formulas of the phosphorescence decay kinetics have been obtained for the statistical distribution of molecules over the rate constants of radiative and non-radiative deactivations of triplet excitations. It is shown that the characters of the phosphorescence decay differ for these two cases. The obtained difference in the kinetics has been used to establish a reason for the deviation from the exponential law and a faster decay of the sensitized phosphorescence of naphthalene and diphenyl in n-paraffin matrices (at T = 77 K) in the presence of heavy dibromo-diphenylene sulfide atoms in the donor.

在三重态激发的辐射和非辐射失活速率下，分子统计分布下的磷光衰变动力学

对于三重态激发的辐射和非辐射失活速率常数，分子的统计分布已经获得了磷光衰减动力学的近似公式。结果表明，这两种情况的磷光衰减特性不同。在重二溴存在下，已获得的动力学差异已被用于建立偏离指数定律和正构烷烃基质中萘和二苯敏化磷光更快衰减的原因（在T = 77 K时）供体中的-二苯撑硫原子。
