THE APPLICATION OF PHOTO-REDUCTION OF THIN CUPROUS IODIDE FILM FOR METAL IMAGE FORMATION

Article abstract of DOI:10.1246/cl.1984.961

The surface chemical properties of cuprous-iodide (CuI) film evaporated on a polymer layer containing a precursor reducing agent, 2-isopropoxy-1,4-naphtoquinone (IPNQ), were markedly affected by UV irradiation.The CuI was reduced by photoproducts of the IPNQ and the surface reductants attracted the zinc vapor in a vacuum evaporation vessel.Thus the UV exposure resulted in the zinc vapor deposition.
