Abstract

A mechanism of the nonlinear absorption response related to the charge transfer in mixed-valence compounds was studied by measuring their spectral and temporal characteristics. It is shown that a photoinduced variation of the absorption response is related to a longwave shift of the IVCT band. A qualitative description of the process is proposed that is based on the model of excitation of a three-band scheme where each level is capable of decaying to the continuum.
