Abstract
Organic light emitting diode (OLEDs) are fabricated using a novel star-shaped hexafluorenylbenzene with a simple structure of indium-tin-oxide (ITO)/1,2,3,4,5,6-hexakis(9,9-diethyl-9H-fluoren-2-yl)benzene (HKEthFLYPh):N, N'-bis-(1-naphthyl)-N,N'-diphenyl-(1,1'-biphenyl)-4,4'-diamine (NPB)/2,9-dimenthyl-4,7-diphenyl-1,10-phenanthroline (BCP)/tris(8-hydroxyquinoline) aluminum (Alq3)/Mg:Ag by spin coating method. The electroluminescent properties of the device are characterized. The results show that there is a new peak at 600 nm, which is no appearance in PL spectra. This new emission is proposed to be electroplex that occurred at the solid-state interface between HKEthFLYPh and BCP in addition to the exciton emission from NPB. The Commissions Internationale De L'Eclairage (CIE) coordinates of the device are (x=0.33, y=0.29) at 10 V, which obviously belongs to white light emission.
