Abstract

The mechanism of photovoltage generation in the micellar solution of nonionic surfactants incorporating thionine dye involves charge-transfer (CT) or electron donor acceptor (EDA) interaction; the dye acts as the electron acceptor and the surfactants act as the electron donors. This is well corroborated by the spectral studies of the systems. The thermodynamic and spectral properties of the complexes are presented. The photovoltage generation, the spectral shifts due to complexation, and the thermodynamic properties of the complexes are found to be well correlated.
