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||ISSN:||1077-3118||DOI:||10.1063/1.2186080||Rights:||© American Institute of Physics||Type:||Article||Affiliation:||Osram Opto Semiconductors, Inc.||Affiliation :||Osram Opto Semiconductors, Inc.|
