摘要：

CoS2 thin films on PA 6 sheets were successfully formed by a two-step adsorption-diffusion method. A solution of pentathionate acid and a solution of Co(II) in complex form were used as a source for the formation of cobalt sulfide films. It has been established that increasing the duration of the first stage of the process, as well as increasing the temperature of the Co(II) precursor solution, plays a decisive role on the surface quality and positive physical properties of the resulting CoS2 films. The surface morphology, physical properties and elemental composition of the obtained CoS2 films have been investigated by means of XRD, SEM/EDS, ICP-OES and AFM. The formed CoS2 thin films exhibit a broad absorption edge with a high absorption coefficient (alpha approximate to 104 cm(-1)). UV-Vis studies of films have revealed a significant influence of film formation conditions on the values of their optical band gap.
