We prepared Ag thin films on glass substrates with an interlayer of 3-mercaptopropyl trimethoxysilane (MPTMS) for use as transparent anodes in organic light emitting diodes (OLEDs) as substitutes for conventionally used tin-doped indium oxide (ITO) films. The measured OLED properties reveal that a Ag (8 nm)/MPTMS film can be used as the anode, despite having inferior optical properties to ITO films. Experiments also revealed that employing a thicker Ag film anode improved the emission properties of OLEDs. These results demonstrate that Ag/MPTMS anodes are promising for producing high-performance OLEDs. (C) 2012 Elsevier B.V. All rights reserved.
