Abstract
Optical properties of zirconium-based amorphous alloys that were subjected to deuterium plasma treatment have been investigated by the multiple-angle-of-incidence single-wavelength and spectral ellipsometry in a spectral range of 0.5–3.5 eV. After bombardment by ions of deuterium plasma of the samples the increase in the intensity of absorption within the spectra of optical conductivity in the indicated spectral range was found. Such behavior of the optical properties can be explained by deuterium plasma ions sputtering of a subsurface layer, and by modification of the electronic properties of a near-surface layer due to deuterium implantation. The optical anisotropy of the samples both in the initial and after treatment in the deuterium plasma was not observed being inherent for amorphous surface layer structures. It has been found that the treatment of mirror-like surfaces by the deuterium plasma increases the roughness of the surface of Zr57Cu15.4Al10Ni12.6Nb5 alloy mirror sample investigated.
