    We have developed highly efficient yellowish-white organic light-emitting devices (WOLEDs) with very broad emission based on a orange emitter, (2-2 '-(4-flurophenyl)benzothiozolato-N,C-2 ') platinum (acetylacetonate) [Pt(F-bt)acac]. A yellowish-white light device with one of the highest electroluminescent (EL) efficiencies of 19.68cd/A (10.94%) with Commission Internationale d'Eclairage (CIE) coordinates of (x,y) = (0.399,0.453) has been demonstrated.
