Spatially Controlled Functionalization and Chemical Manipulation to Fabricate 2D Arrays of Gold Nanoparticles onto ITO

摘要

Immobilization of gold nanoparticles (AuNts) onto new generation of advanced electronic and optical materials are currently being investigated for their potential applications such as light emitting diodes, organic optoelectronic devices and chemical/biological sensors [1,2]. The functionalization of Indium Tin Oxide (ITO), which is a conductive optical transparent material, has been the subject of intense interest. Particularly, the immobilization of AuNts onto ITO has attracted the attention of several researchers [3,4] due to their optoelectronic applications. In this study, we demonstrate the formation of 2D arrays of AuNts by controlled functionalization in regular linear fashion based on self-assembly and Vacuum ultraviolet (VUV) lithography approaches.
