Electro-optical induction of recombination luminescence in an organic photoconductor

Recombination luminescence has been observed in particle dispersions of an organic photoconductor (x-H2Pc) by a new electro-optical technique that eliminates the need for double injection electrodes. The method permits independent investigations to be made of the charge carrier photogeneration and recombination processes in a single sample of photoconducting material.
