High photon conversion in a light transducer combining organic electroluminescent diode with photoresponsive organic pigment film

Abstract
An all‐organic light transducer based on a hybridization of an organic electroluminescent diode and a perylene pigment film as an electron photoinjecting electrode has been successfully designed. The quantum efficiency of photon conversion from red to red light reached 40% with the assistance of effective electron photoinjection due to large photocurrent multiplication in a photoresponsive perylene film.
