Abstract

ZrO₂ thin films were prepared by sol-gel technology from suitable zirconia aqueous colloidal suspensions containing nano-crystalline ZrO₂ at room temperature synthesized by hydrothermal process from inorganic precursor (ZrOCl₂ (DOT) 8 H₂O). By adding a soluble organic binder PVP to the suspension prior to application, it substantially increased the coating refractive index and the abrasion- resistance as well as the laser damage threshold. The features of the coatings and the colloidal suspensions were investigated. Multilayer highly reflective dielectric coatings were also elaborated by laying down quarterwave- thick alternating coatings of the binder-aided zirconia and silica, which was prepared with the sol-gel process from TEOS. Laser damage thresholds of 20 and 18 J/cm² (1064 nm, 1 ns) were achieved for single ZrO₂-PVP coating and ZrO₂-PVP/SiO₂ multilayers respectively.
