AZO-coated Glass Description
AZO-coated glass refers to aluminium-doped zinc oxide (ZnO) used as a transparent, conductive glass. The transparent conductive ZnO:Al layer is produced by doping aluminium into the ZnO system. Doping increases the film’s conductivity, and the stability of the transparent conductive AZO film exceeds that of ITO in hydrogen plasma. It exhibits improved optical performance in the infrared range compared with ITO. The production process is straightforward given that aluminium is more abundant than indium, and the material is non-toxic. Consequently, AZO-coated glass is increasingly used as a substitute for ITO film.
