Abstract
An antireflection (AR) coating is fabricated by applying an optimal
spin-coating method and a pH-modified SiO2 nanoparticle
solution on a cover glass. Because the pH value of the solution will
affect the aggregation and dispersion of the SiO2 particles,
the transmittance of the AR-treated cover glass will be enhanced under
optimal fabricated conditions. The experimental results show that an AR
coating fabricated by an SiO2 nanoparticle solution of pH 11
enhances the transmittance approximately by 3% and 5% under normal and
oblique incident conditions, respectively. Furthermore, the AR-treated
cover glass exhibits hydrophobicity and shows a 65% enhancement at a
contact angle to bare glass.
