中文摘要	the photoluminescence properties of one europium complex eu(tenb)(3)phen (tfnb = 4,4,4-trifluoro-1-(naphthyl)-1,3-butanedione, phen = 1,10-phenanthroline) doped in a hole-transporting material cbp (4,4'-n,n'-dicarbazole-biphenyl) films were studied. a series of organic light-emitting devices (oleds) using eu (tenb)(3)phen as the emitter were fabricated with a multilayer structure of indium tin oxide, 250 omega/square)/tpd (n,n'-diphenyl-n,n'-bis(3-methyllphenyl)-(1,1'-biphenyl)-4,4'-cliamine, 50 nm)/eu(tenb)(3)phen (x): cbp (4,4'-n,n'-dicarbazole-biphenyl, 45 nm)/bcp (2,9-dimethyl-4,7-diphenyl-1,10 phenanthroline. 20 nm)/aiq (tris(8-hydroxy-quinoline) aluminium, 30 nm)/lif (1 nm)/al (100 nm), where x is the weight percentage of eu(tenb)(3)phen doped in the cbp matrix (1-6%). a red emission at 612 nm with a half bandwidth of 3 nm, characteristic of eu(iii) ion, was observed with all devices. the device with a 3% dopant concentration shows the maximum luminance up to 1169 cd/m(2) (18 v) and the device with a 5% dopant concentration exhibits a current efficiency of 4.46 cd/a and power efficiency of 2.03 lm/w. the mechanism of the electroluminescence was also discussed.
