PDMS antireflection nano-coating for glass substrates

A new anti-reflective nano-coating for glass surfaces working in the visible and near infrared optical spectrum was developed and characterized. The nano-coating is realized by means of a self-assembly technique which creates a single layer of nano-hemispheres, realized in polydimethylsiloxane (PDMS). The coating layer is then placed on a flat glass surface to measure the transmission improvement at different wavelengths. Through this novel approach we achieve 1% enhancement of the light transmission at normal incidence, for a single glass surface, in most of the visible and near-infrared spectral range.
