Abstract:An indium-tin-oxide (ITO)-free flexible organic light-emitting device (OLED) with improved efficiency has been demonstrated by employing a template stripping process to create an ultrasmooth PEDOT: PSS anode on a photopolymer substrate. The device performance has been improved owing to lowered surface roughness of the PEDOT: PSS anode. A 38% enhancement in efficiency has been obtained. The ITO-free OLEDs on the polymer substrate have shown flexibility, and the device is free of cracks and dark spots under small bending radius. Moreover, the elimination of the H2SO4 residues on the surface of the H2SO4-treated PEDOT: PSS by the template stripping has demonstrated its beneficial effect on the device stability.
Keywords:Organic light-emitting devices  Flexible  Ultrasmooth PEDOT: PSS anode  Template stripping
