Abstract
Silver nanoparticle thin films were deposited on glass substrates by electrostatics spray deposition. Electrostatic spray condition was optimized by varying distance between nozzle and substrate between 20 mm and 60 mm, deposition time was fixed at 5 minute. The surface morphology and optical properties of films were carried out by using Atomic Force Microscope (AFM), Field Emission Scanning Electron Microscopy (FE-SEM) and UV-Vis Spectrophotometer. The results is indicate that the surface morphology of silver nanoparticle thin film show the grain size of film near around 100 nm at distance between nozzle and substrate of 60 mm and the RMS roughness decreases from 9.59 nm to 2.35 nm when distance between nozzle and substrate was increased from 20 mm to 60 mm. The optical absorption spectra showed the main absorption peak at 436 nm. When the distance between the nozzle and the substrate raise, decrease in absorption has been observed. © (2010) Trans Tech Publications.
