摘要	Electroluminescence (EL) devices, using 4, 4',4"-tris (2-methylphenyl-phenylamino) triphenylamine (m-MTDATA) as holetransporting material and bathocuproine (BCP) as an electron-transporting material, were fabricated, which emitted bright green light peaked at 520nm instead of the emission of m-MTDATA or BCP. It was attributed to the exciplex formation and emission at the interface of m-MTDATA and BCP. EL performance was significantly enhanced by a thin mixed layer (5 nm) of m-MTDATA and BCP inserted between the two organic layers of the original m-MTDATA/BCP bilayer device. The trilayer device showed maximum luminance of 1,205cd/m(2) at 8V. At a luminance of 100cd/m(2), the power efficiency is 1.64cd/A. Commission International De L'Eclairogye (CIE) color coordinates of the output spectrum of the devices at 8 V are x=0.244 and y=0.464. These devices also showed photovoltaic (PV) properties, which were sensitive to UV light. The PV diode exhibits high open-circuit voltage (V-oc) of 2.10V under illumination of 365nm UV light with 2mW/cm(2). And the short-circuit current (I-sc) of 92.5 x 10(-6) A/cm(2), fill factor (FF) of 0.30 and power conversion efficiency (eta(e)) of 2.91% are respectively achieved. It is considered that strong exciplex emission in an EL device is a good indicator of efficient charge transfer at the organic interface, which is a basic requirement for good PV performance. Both the bilayer and trilayer devices showed EL and PV properties, suggesting their potential use as multifunction devices. (c) 2006 Elsevier B.V. All rights reserved.
