Equations relating the radiative and nonradiative decay rate constants of singlet excitons in super-radiant aggregates to the relative intensities of the 0–0 and 0–1 peaks in the emission spectrum were derived and tested against experimental data. In many instances, these equations eliminate the need for a time-dependent fluorescence decay measurement. They can also be useful in determining the fluorescence quantum yield.

从发射光谱中提取超辐射J-聚集体的辐射和非辐射速率常数

推导了有关超辐射聚集体中单重态激子的辐射和非辐射衰变速率常数与发射光谱中0-0和0-1峰的相对强度的关系式,并针对实验数据进行了测试。在许多情况下,这些方程式无需进行随时间变化的荧光衰减测量。它们还可用于确定荧光量子产率。
