We demonstrate coaxial-aperture-based plasmonic nanostructures for tunable plasmon resonances in optically thick metal films. Accurate control of etching depth is achieved via cross-section investigation under a scanning electron microscope. Colorful surfaces are observed with varying geometries. The approach developed in this work is potentially useful for optical devices design and development in...
In this study, a three-dimensional (3D) graphene/ZnO nanorod (G/ZnO) composite was synthesized by chemical vapor deposition (CVD) and simple hydrothermal method. Integration of 3D graphene and ZnO nanorods leads to a high performance in photocatalytic degradation toward methyl orange (MO). The results indicate that the 3D G/ZnO composite achieves a higher degradation efficiency under UV light than...
