Non-Exponential Luminescence Intensities in Exciton Trapping: Quantitative Comparison for Triplets in 1,2,4,5-tetrachlorobenzene
Questions regarding the dynamical information available in sensitized luminescence experiments are addressed specifically for triplet excitons in the quasi-one-dimensional system 1,2,4,5-tetrachlorobenzene (TCB). Using a recently developed generalized-master-equation theory of exciton trapping we analyze the observed time-dependent phosphorescence data from pure and mixed crystals of TCB. The consistency of the trapping data with recent spin echo measurements on TCB is discussed and the necessity of involking time-dependent energy transfer rates is carefully examined in the specific context of this system.
