Abstract


In this study, prepared using colloidal crystal template method of 3D ordered macroporous (3DOM) Cu 2 O film and to characterize its performance . Using colloidal microspheres in the 200-600nm monodisperse polystyrene (PS) by the particle size of the emulsion obtained by the method , the use of vertical deposition method to make the microspheres since been assembled PS colloidal crystal template . Electrochemical deposition of Cu 2 O fill the gap to the template . Using organic solvent tetrahydrofuran for 2 h to remove the PS template 3DOM Cu 2 O film . Spectroscopy ( Energy Dispersive Spectrometer will , EDS ) , X - ray diffraction ( X-ray Diffraction , XRD ) and X - ray photoelectron spectroscopy (X-Ray Photoelectron Spectroscopy, XPS) obtained directly on the ITO conductive glass substrate electrodeposition a component of a film material characterization results show that using the electrochemical test method in an aqueous system Cu 2 2 O crystals; > O the cathodic electrodeposition process , by the cyclic voltammetry (CV) curve to determine the deposition potential , the current - time (It) curve reflects Cu 2 O electrodeposition process current changes . Using atomic force microscopy ( Atomic Force Microscope , AFM ) and scanning electron microscopy (Scanning Electron Microscope, SEM) direct electrodeposition on ITO conductive glass substrate Cu 2 O thin film \u0026 3DOM Cu , 2 O morphology of the films were characterized . Electrodeposition process (pH, deposition potential , deposition time and temperature of the electrolyte , etc.) on the the direct electrical deposited Cu 2 < / sub> O film and 3DOM Cu 2 O film morphology the impact , and the template ( microsphere size , arrangement , and defects ) 3DOM Cu 2 O film morphology . The results show that , in the experimental range , control of experimental conditions , can be prepared by the of rendering highly ordered three-dimensional macroporous morphology 3DOM Cu 2 O film . With the spectral analysis were used to analyze the PS / Cu 2 O composite film and the 3DOM the of Cu 2 O film spectral characteristics . The impact of the colloidal crystals microsphere size , angle of incidence , and factors such as the location of the photonic bandgap .
