|Keywords:||Light emitting diodes;Phosphorescence;Phosphors;Radiation||Issue Date:||2006||Publisher:||American Institute of Physics||Source:||Applied physics letters, 2006, Volume 88, Issue 11, Pages 1-3||Abstract:||We present a highly efficient white electroluminescence device by the combination of a solution processed blue organic phosphorescence light-emitting diode with appropriate down-conversion phosphor system. The use of this down-conversion system produced an extraordinary enhancement on device performance, resulting in a white electroluminescence device with luminance efficacy of 25 lm/W at luminance efficiency reaching 39 cd/A. The extraordinary enhancement on device performance is attributed to isotropic radiation pattern of the excited phosphor particles, leading to high light extraction properties||URI:||http://ktisis.cut.ac.cy/handle/10488/7617||ISSN:||0003-6951 (print)
