Characterization and Optical Absorption Property of Cu2S Nano-Films Prepared by Hydrothermal Method on Cu Foil
Abstract: Cu2S nano-films were synthesized on copper foil with TAA as sulfur sources by hydrothermal method. The effect of the different additions on structures, morphology and UV-vis absorption property of the films has been studied by X-Ray Diffraction (XRD), Scanning Electron Microscope (FESEM) and Infrared (IR) spectra and UV-vis absorption spectroscopy. The results show that the crystallinity and morphology of the Cu2S with orthogonal structure depended on the additions. The formation of the films was thought to come from the interaction between the additions and the reactants under the hydrothermal conditions. The UV-vis absorption spectra and the (αhν)2-hν curves suggest that the calculated band gap values indicated the distinct blue shift compared to that of the bulk Cu2S, which is attributed to the stronger quantum confinement effects than the Coulomb term.
