Abstract
Wereport on a simple plasma electrochemistry method for synthesizing cuprousoxide(Cu2O) nanoparticles in the presence of glucose. In this system, Ar plasmain contact with aNaCl solution was used as one electrode, and a Cu plate wasimmersed in the solution as thecounter electrode. The plasma-solution interactionproduced many reducing and oxidizingspecies which can react with the Cu ionsreleased from the Cu electrode. Cu2O nanoparticles,with an average diameter of22 ±6nm, were formed under the competition of reducing andoxidizing reactions in thesolution. The results show that the glucose added in the electrolytestronglyinfluences the properties of the products. Corresponding to high, medium,andlow concentrations of glucose, the products were nanoparticles fromamorphous Cu2O,polycrystalline Cu2O, and a mixture of polycrystalline Cu2O andCu2Cl(OH)3, respectively.

Abstract
Optical behaviors of bothpolycrystalline silicon (Si) and gallium arsenide (GaAs)nanocone (NC)-cappednanowire (NW) arrays are systematically investigated and a fulllight managementpicture is presented. The study demonstrates that compared to shapeandenvironment-sensitive optical resonance modes, including leaky modes andguidedlongitudinal resonances, optimization of light harvesting based on lightscattering is moreoperable to guide related device fabrication. Under thisconsideration, near 100% absorptionabove the bandgap energy is realized forGaAs NC-capped NW arrays with an effectivethickness of only ~1000 nm throughbalancing antireflection and light scattering in the opticalsystems. Furtherstudy under oblique incidence shows that light absorption for theoptimizedNC-capped NW arrays is almost insensitive to the incident angle, indicatingexcellentomnidirectional light management in the NC-capped NW configuration.
