Photon echoes in doped organic amorphous systems over a wide (0.35-50 K) temperature range
TL;DR: In this paper, a comparison of the high-temperature part of the line broadening of two dye molecules (ZnTPP and Res), embedded in the same matrices (EtOD and EtOD 6 ) showed that the optical dephasing is determined by two contributions of the dynamics of matrix itself and the dynamics which is related to the doped molecules.

Line broadening mechanisms in spectra of organic amorphous solids: photon echo study of terrylene in polyisobutylene at subkelvin temperatures
TL;DR: In this article, a two-pulse photon echo investigation of the amorphous polymer polyisobutylene (PIB) doped with tetra-tert-butylterrylene (TBT) in the temperature region 0.4-4 K is presented.
