Summary: | O4; We demonstrate the near-infrared(NIR)organic light-emitting devices(OLEDs)based on copper hexade cafluorophthalocyanine(CuPcF16)doped into 2,2,2"-(1,3,5-benzenetriyl)tris-[1-phenyl-1H-benzimidazole](TPBI).The device structure is ITO/NPB/TPBI:CuPcF16/BCP/Alq3/Al.Room-temperature electro luminescence is observed at about 1106 nm due to transitions from the first excited triplet state to the ground state(T1-S0)of CuPcF16.The result indicates that F(o)rster and Dexter energy transfers play a minor role in these devices,while the direct charge trapping is the dominant mechanism.The absorption spectra of CuPcF16 solution in pyridine and vacuum sublimed films on quartz have also been investigated. |
