摘要
Blue emission from polymer blends composed of poly(2,5-dibutoxyphenyiene)(PPP)in a matrix polymer poly(N-vinylcarbazole)(PVK)is reported.The light-emitting layer can be fabricated by spin-coating of PPP-PVK blend solution without subsequent processing or heat treatment.A cell structure of glass substrate/indium-tin-oxide/PPP-PVK blend/aluminum is employed.Blue light emission with a peak position at 448nm occurs at a bias of about 8V.
