Abstract:A monodisperse alcosol containing 0.1 wt. % 15 nm gold particles was subjected to controlled flow through a metal capillary exposed to an electric field at the ambient temperature to generate an electrohydrodynamic jet, which subsequently disintegrated into droplets. A silicon substrate was used to collect the droplets and prepare gold films. By varying the deposition time, we have prepared gold films in the thickness range of ∼500–∼ 2000 nm in a maximum spray time of 450 s. This is a significant achievement considering the initial concentration of gold and the spray time involved. The characteristics of the jet, droplets and films prepared were evaluated using advanced analytical techniques. PACS 81.15.Rs; 81.15.-z; 81.07.-b; 81.20.-n; 68.55.jd
