Electron transfer between thionine dye and ZnO semiconductor in variety solvents

Abstract EN

Electron transfer rate constant for dye / semiconductor system has been calculated using Fermi golden rule .The reorganization energy (λ eV) is calculated for this system at three solvents and compared with the theoretical and experimental values.

The effective free energy ( ΔGo eV) is calculated depending on the spectrum of thionine dye.

The transfer is treated according to the weak coupling between semiconductor and acceptor molecule state.

Our calculations show good agreement with the theoretical and experimental observed results.
