Abstract :Light emitting properties of poly[4-insert ignore into journalissuearticles values(5-insert ignore into journalissuearticles values(biphenyl- 4-yl);-4-hexylthiophen-2-yl);-2-dodecyl-7-insert ignore into journalissuearticles values(4-hexyl-thiophen-2-yl);-2H-benzo[d][1,2,3]-triazole] insert ignore into journalissuearticles values(PPhHTBT); and polyinsert ignore into journalissuearticles values(9-vinylcarbazole); insert ignore into journalissuearticles values(PVK); blends were investigated with a configuration of ITO/PEDOT-PSS/BLEND/Ca/Al in ratios ranging from 5 to 100 wt% in PPhHTBT. Thin film and solution spectra of all blends revealed that energy transfer was completely achieved. Device performance increased for all blends and reached 1.1 cd/A for 30 wt% PPhHTBT.
