Abstract Light-induced reactions of poly-Cu with Cl2 and the formation of CuCl x films were studied in the spectral range of 105–400 nm by using synchrotron radiation. The efficiencies of the reactions with Cl2 pressures between 10−5 and 10−2 mbar were determined from the height distributions of spatial structures in the CuCl x films. The heights typically range from 10 to 104 nm. An efficiency of about 107 CuCl x molecules per dissociated Cl2 molecule is observed at high Cl2 exposures. At low Cl2 pressures CuCl x formes anisotropically in the irradiated area. The efficiency is determined by light-induced surface processes supporting the build up of CuCl x in the long wavelength range and competing processes at short wavelengths which reduce the efficiency.
