Description
Summary:A time-resolved measurement system for electrofluorescence spectra (plots of electric-field-induced change in fluorescence intensity as a function of wavelength) has been constructed by combining the time-correlated single-photon-counting system for emission decay measurement with modulated electric field as a sample bias. Four fluorescence decays, which correspond to positive, zero, negative, and zero sample bias, respectively, can be measured simultaneously, and a small field-induced change in decay profile can be detected precisely by using the constructed system. Measurements of time-resolved electrofluorescence spectra have been performed in electron donor–acceptor compounds which show a photoinduced electron transfer.
