摘要：

Green and bluish-green organic light emitting diode (OLEDs) devices based on Ir(tfmppy)2(tpip) [1, tfmppy=4-trifluoromethylphenylpyridine, tpip=tetraphenylimido-diphosphinate] and Ir(dfppy)2(tpip) [2, dfppy=4, 6-difluorophenylpyridine] as emitters were constructed with the device structure of ITO/TAPC (1, 1-bis[4-[N, N- di(p-tolyl)amino]phenyl]cyclohexane, 60 nm)/Ir(III) complex (x%, mass fraction):SimCP (3, 5-bis(9-carbazolyl)tetraphenylsilane, 40 nm)/TPBi (2, 2′, 2″-(1, 3, 5-benzinetriyl)-tris(1-phenyl-1-H-benzimidazole, 60 nm)/LiF (1 nm)/Al (100 nm). Green device with 6% 1 doped concentration showed a maximum current efficiency of 47.10 cd/A at 5 930 cd/m2, a maximum brightness of 38 674 cd/m2 at 16.4 V with (0.28, 0.65) at Commission Internationale de L'Eclairage (CIE) coordinates. Bluish-green device with 10% 2 doped concentration exhibited a current efficiency of 14.80 cd/A at 3 175 cd/m2, a brightness of 25 985 cd/m2 at 11.8 V CIE coordinates of (0.15, 0.50).
