Abstract

Optoelectronic devices based upon poly[2-methoxy-5-(2-ethylhexyloxy)-1,4-phenylenevinylene](MEH-PPV) -single-walled carbon nanotube (SWCNT) nanocomposites have been fabricated and characterized. SWCNTs were synthesized by the laser ablation method, and organic thin films were produced by spin-coating and cluster beam deposition (CBD) methods. The hole-only-type devices with the structure of ITO-coated glass/PEDOT:PSS/nanocomposite/Au demonstrate that the transport characteristics are improved due to the efficient hole injection and percolative conduction in the range of 0-1.0 SWCNT wt. % relative to MEH-PPV. Studies of luminescence and device characteristics for the double-layer-type devices of ITO-coated glass/PEDOT:PSS/nanocomposite/(DCM-doped)Alq3/Li:Al exhibit that the incorporation of SWCNT into MEH-PPV and of DCM into Alq3 enhances the transport characteristics and device performance, respectively
