Abstract

Silver nanoparticles have been obtained by photoreduction from solutions during the last two decades, but the growth of differently structured silver nanoparticles directly onto transparent substrates has not been a major area of research. An analysis of silver deposition on glass substrates has shown that the density of nanoparticles deposited on glass substrates increases when a (3-aminopropyl)triethoxysilane coating is applied to the glass surface. Furthermore, the density and structure of the nanoparticles can be controlled by varying the laser illumination intensity. This fabrication method has potential applications in surface enhanced Raman spectroscopy, surface plasmon resonance sensing, and direct patterning of functional materials.
