摘要
Vibrationally resolved dispersed fluorescence spectra of single molecules of terrylene in polyethylene at 1.5 K are presented. Most of the almost-equal-to 35 individual molecules examined show spectra very similar to those of the bulk sample, with only small frequency shifts and intensity variations. Several molecules with a different frequency and intensity pattern are also observed. After considering many possibilities, we tentatively conclude that the two types of spectra arise from terrylene molecules located in the amorphous and crystalline regions of the polyethylene matrix.
