| Abstract | Reducing the reflective nature of a substrate will improve the performance of the optical devices and other devices which can detect light. Extensive studies for the minimization of reflectance involving nanotechnology have resulted in improvising the anti-reflection coatings in a significant way. In this work, anti-reflective coatings using titanium and zinc metal oxide nanoparticles are layered on glass substrates to improve the optical properties. Thin films of nanoparticles are coated on individual glass substrates using the Spark deposition technique and these samples are investigated for optical properties using a simple method of UV-Visible spectroscopy without requiring a study of refractive indices of individual nanoparticles. The nanostructures of the metal oxide nanoparticles and films are characterized using Scanning electron microscope (field emission). Water contact angles of the surfaces formed by metal oxide thin films on glass substrates are measured using a digital microscope. Comparisons between the particle size, film thickness, optical transmittance and the surface wettability of the thin films deposited at different conditions are reported in this work. |
