Direct patterning of nickel films on glass substrates

A new approach to form patterned Ni films on the glass substrates has been proposed. The patterning is based on the photo-sensitivity of organically modified nickel gel films. The combination of acetol and monoethanolamine was found to show the excellent dissolution of nickel acetate to 2-propanol. The gel films prepared from this solution have a photosensitivity, showing the significant decrease in the absorbance and solubility when they were irradiated by UV-light. Using this property of the gel films very regular nickel patterns were successfully made on the glass substrate.
