Mz. Tian et al., THERMALLY ACTIVATED BARRIER CROSSING AND HOLE-FILLING IN DONOR-ACCEPTOR ELECTRON-TRANSFER SYSTEMS, Journal of luminescence, 64(1-6), 1995, pp. 131-134
An electron donor-acceptor-doped polymer for photon-gated spectral hol
e burning (PHB) was described as a two-level system (TLS). Thermal hol
e-filling was studied by the temperature cycling experiment. A thermal
ly activated barrier crossing model in a TLS is used to explain the ho
le-filling process was verified by numerically fitting between the the
oretical and the experimental results. The maximum barrier heights in
several PHB materials were obtained.
