dc.description.abstractAn alternating triarylamine-functionalized fluorene-based copolymer synthesized using a Suzuki-Miyaura cross-coupling procedure is used as blue emitting layer in polymer light-emitting diodes (PLEDs). Subsequently, the effects of CdSe/ZnS quantum dots (QDs) on the optoelectronic properties of the copolymer are investigated. Therefore, CdSe/ZnS QDs are embedded into the copolymer matrix and hybrid PLEDs are fabricated. The devices comprised of CdSe/ZnS QDs reveal enhanced performances, yielding about 3.4 times more luminous efficiency than that of the device without QDs. Further enhancement is achieved by using electron transport layer; the luminous efficiency rose from 0.065 to 1.740 cd A(-1) for the hybrid PLEDs, corresponding to a superb 27-fold intensification of the efficiency.
