Abstract

The electric field modulation of time resolved fluorescence has been studied in a N,N' bis(methyl)perylene 3,4,9,10 tetracarboxyl diimide. It was found that fluorescence is multiphasic in nature which was interpreted in terms of energy transfer from host molecules to defect sites. Analysis of the experimental data showed that the application of the electric field leads to an increase in the decay rate of fluorescence but leaves the initial fluorescence intensity unchanged. These results indicate that true intrinsic carrier generation process exists which occurs by electric field assisted dissociation of the first excited singlet state.
