This paper reports solution-processed, high-efficiency polymer light-emitting diodes fabricated by a new type of roll-to-roll coating method under ambient air conditions. A noble roll-to-roll cohesive coating system utilizes only natural gravity and the surface tension of the solution to flow out from the capillary to the surface of the substrate. Because(More)
The dielectric/metal/dielectric multilayer is suitable for a transparent electrode because of its high-optical and high-electrical properties; however, it is fabricated by an expensive and inefficient multistep vacuum process. We present a WO3/Ag/WO3 (WAW) multilayer transparent anode with solution-processed WO3 for polymer light-emitting diodes (PLEDs).(More)
In this work, we use the electrical method to coat graphene oxide (GO) on ITO (Indium Tin Oxide) glass. The coated GO was characterized by Raman spectroscopy and X-ray photoelectron spectroscopy (XPS). The coated surface was monitored by scanning electron microscope (SEM) and atomic force microscope (AFM). Based on this coating method, we can control the(More)
