Various oxide films were prepared by oxygen ion-assisted deposition. The ion source (Mark II Gridless Ion source, manufactured by Commonwealth Scientific Corp.) uses the End-Hall configuration and generates high-current, low-energy beams of ions. Films of TiO2, SiO2, Al2O3, Y2O3 were deposited on substrates in temperatures ranging from ambient to 200 degree(s)C. The films had a high index of refraction, were hard and adhered strongly to the substrates, as compared to conventionally deposited oxide films. Multilayers of TiO2/SiO2 were prepared giving hard and environmentally stable coatings.
