Description |
We have synthesized a new aluminium complex, [5-choloro-8-hydroxyquinoline] bis[2,2'bipyridine] Aluminium Al(Bpy)(2)(5-Clq) and characterized it for structural, thermal and photoluminescence properties. The prepared material was characterized by Fourier transformed infra-red spectroscopy (FTIR), thermal gravimetric analysis (TGA) and photoluminescence. The prepared material showed thermal stability up to 240 degrees C. The photoluminescence spectrum of Al(Bpy)2(5-Clq) in toluene solution showed peak at 515 nm. This material was used as an emissive layer in organic light emitting diodes (OLEDs). The fundamental structure of device is ITO/F4-TCNQ(1 nm)/alpha-NPD(35 nm)/Al(Bpy)(2)(5-Clq) (35 nm)/BCP(6 nm)/Alq(3)(28 nm)/LiF(1 nm)/Al(150 nm). The device emits an yellowish green light (CIE coordinates, x = 032, y = 0.52) with maximum luminescence 314 Cd/m(2) at 18 V. The maximum current efficiency of OLED was 0.09 Cd/A and maximum power efficiency was 0.03 lm/W at 9 V respectively. (C) 2015 Elsevier B.V. All rights reserved.
