A study of carrier generation mechanism in x -metal-free phthalocyanine

Abstract

Combined pulsed photoconductivity and electric field induced fluorescence quenching measurements have been used to study carrier generation mechanism in x-metal-free phthalocyanine. It was found that at low fields fluorescence quenching is a quadratic function of the applied field and saturates at unity at very high fields. Carrier generation is finite at zero applied field and has a linear component at low fields. Linear correlation between …
