Studying the Effect of Silica Nanoparticles on Optical Properties of Polyvinyl Alcohol Thin Films for Semi-conductors Applications
Abstract
This search includes measurement of some optical properties of Polyvinyl alcohol thin film such as absorbance, transmittance, coefficient of absorbance, and refraction index via Spectrophotometer Spectroscopy (UV-1800. The effect of Silica nanoparticles on these properties were also studied. Imaginary and real Dielectric constant of samples were calculated.
The results showed that all these propertiesincreased linearly by adding of 5% of silica nanoparticles except the transmittance has versus behavior of absorbance.
