Index-tunable anti-reflection SiO2 coatings prepared on the surface of VO2 films by sol–gel dip-coating technique to enhance the visible and infrared transmittance of SiO2/VO2 films.
Doped ZnO:Al thin films were deposited on glass substrates by the solgel dip technique. Optical parameters such as the refractive index and the extinction coefficient tend to change with increasing annealing temperature.
