  Amorphous thin layers with non-stoichiometric chemical composition AS33$67 (AsS2) have been prepared by spin coating. This particular deposition technique is a very promising, low-cost technique, to create optical-grade, chalcogenide glass thin films, which are certainly ideal for visible and infrared applications. The layer thickness and optical constants have been first determined by the Swanepoel transmittance-envelope method, for the case of uniform thin films, with an accuracy better than 1%. The refractive-index dispersion has been analyzed on the basis of the Wemple-DiDomenico single-effective oscillator model: n(2)(E) = 1 + EoEd/(E-0(2)- E-2), where E-0 is the single-oscillator energy and Ed the dispersion energy. The strong-absorption region of the absorption edge is described using the 'non-direct electronic transition' model, proposed by Tauc. Structural information of the AsS2 bulk and thin-layer samples has been gained from X-ray diffraction measurements, and, also, from the analysis of the refractive-index dispersion. In addition, the simulation software WVASE32 was successfully utilized in fitting the experimental, normal-incidence transmission data by the use of Tauc-Lorentz model; an excellent fit between the measured and software-generated optical transmission spectra has been generally achieved, with a mean-squared-error as low as around 0.4.

  Nuclear magnetic resonance (NMR) of Cu-63 and nuclear quadrupole resonance (NQR) of As-75 ave been used to study relaxation effects and the possibility of local atomic diffusion in the Cu-As-S and Cu-As-Se glassy systems. The frequency and temperature dependences of the spin-lattice and spin-spin relaxation times have been measured. The NMR spin-lattice relaxation measurements for Cu-63 in the Cu-As-Se and Cu-As-S glassy systems suggest that the spin-lattice relaxation rate T1(-1) is probably dominated by two relaxation mechanisms depending on the temperature. For T < 300 K, T1(-1) for Cu-63 and As-75 exhibits a weak temperature dependence, which has been frequently observed for As-75 in the chalcogenide glasses and many other nuclei in the oxide glasses. For T > 300 K, on the other hand, a much more efficient relaxation mechanism takes over where both T1(-1) and T2(-1) increase rapidly with temperature. We suggest that this sudden decrease in the relaxation times is probably due to the local diffusion of Cu. The dramatic decrease of T2 with temperature for T > 300 K is anomalous and may be related to clustering of copper atoms in these glasses.
