Antireflective Effects on a Soda-Lime Glass Induced by Ar+ Implantation

The results of optical and chemical investigations on the anti‐reflective layers obtained by Ar+ implantation on a soda‐lime fiat glass are presented and discussed. The antireflective effect is ascribed to the appearance of an interferential layer with a perturbed refractive index and a lower Na content than the bulk glass and can be optimized by choosing a suitable range of implantation energies and doses. Sodium depth profiles were measured with the 23Na(p, α)20 Ne nuclear resonance reaction and the results compared with the information provided by the specular reflectance curves.
