Abstract:
Color-stable, high-efficiency fluorescent pure-white organic light-emitting diodes were fabricated using an electroluminescence-efficient blue host 2-(N,N-diphenylamino)-6-[4-(N,N-diphenylamino)styryl]naphthalene and yellow 5,6,11,12–tetra-phenylnaphthacene in a single emissive layer. The resultant power efficiency, at 100cd∕m2, for example, was 9.5lm∕W, and its emission changed from (0.321, 0.357) to (0.315, 0.344) for brightness increasing from 100to10000cd∕m2. The high color stability may be attributed to the device structure enabling the generation of excitons on host so that lesser excitons would form on guest, preventing exciton-quenching-caused blueshift.
