Nanocomposite films consisting of a sol–gel hybrid organic–inorganic matrix incorporating ZnS nanocrystals (NCs) have been developed. The nanocomposites films have high visible transparency, enhanced refractive index and photochemical stability. Usage of the diphenyldimethoxysilane and of the ZnS NCs at different concentrations allowed tuning the optical characteristics. Hybrid matrix, NCs and nanocomposite films were characterized by X-Ray Diffraction, High Resolution Transmission Microscopy, spectroscopic ellipsometry, UV–visible and Fourier Transform Infrared Spectroscopy. Applications of nanocomposite films are being investigated as a stable coating for optical purposes.

Abstract
Nanocomposite films consisting of a sol–gel hybrid organic–inorganic matrix incorporating ZnS nanocrystals (NCs) have been developed. The nanocomposites films have high visible transparency, enhanced refractive index and photochemical stability. Usage of the diphenyldimethoxysilane and of the ZnS NCs at different concentrations allowed tuning the optical characteristics. Hybrid matrix, NCs and nanocomposite films were characterized by X-Ray Diffraction, High Resolution Transmission Microscopy, spectroscopic ellipsometry, UV–visible and Fourier Transform Infrared Spectroscopy. Applications of nanocomposite films are being investigated as a stable coating for optical purposes.Pubblicazioni consigliate
