Abstract
Experimental data is presented for singlet exciton transport in a ternary naphthalene system (C10H8/C10D8/BMN). The trapping probability varies with guest concentration and with temperature. The data at 4.2 K are consistent with a generalized diffusion treatment such as that proposed by Gochanour, Andersen, and Fayer. The 1.8 K data conform to a quasistatic percolation model. The supertrap induced energy funnels which might affect this energy transport are limited to nearest neighbors. The BMN fluorescence spectra are affected by exciton–phonon interactions similar to Herzberg–Teller couplingKeywords
