Photon Echoes in an Impurity Polymer: New Data on the Low-Temperature Processes of Phase Relaxation and Their Relationship to the Broadening of Zero-Phonon Lines of Single Molecules

摘要

New experimental data on the times of phase relaxation in the amorphous polyisobutylene doped with chromophore molecules of tetra-tert-butylterylene are obtained by the incoherent photon echo method at temperatures of 5, 7, 10, and 15 K. A comparative analysis of the results is performed and data on the widths of zero-phonon spectral lines of single molecules in this impurity system are presented.
