Up-conversion of red light to green by a new type of light transducer using organic electroluminescent diode combined with photoresponsive amorphous silicon carbide

Abstract
Light up-conversion from red to green was performed in a new type of light transducer composed of an organic electroluminescent diode and a photoresponsive amorphous silicon carbide (a-SiC:H) film as an electron photoinjecting electrode. Quantum efficiency of photon conversion reached 1% with the assistance of newly observed photocurrent multiplication in a-SiC:H film.
