Controllable fabrication of one-dimensional ZnO nanoarrays and their application in constructing silver trap structures

摘要: Large-scale one-dimensional (1-D) ZnO nanoarrays (NAs) with controllable density and diameter have been successfully fabricated on silver plated aluminium through a simple, low-temperature, two-step strategy. Besides, the trap structures constructed based prepared 1-D NAs as building blocks their performance in secondary electron yield suppression were discussed. X-ray diffraction energy dispersive spectrometry morphologies of characterized by scanning microscopy clarified that, for as-obtained, increased vertical alignment improved concentration reactants aqueous solution. The average individual nanorod varied both reactants. Increasing dip-coating times was an effective way to get higher better under same conditions. Meanwhile, uniform dense good PET cloth stainless steel mesh utilizing this As structures, there no obvious differences NAs' before after construction. However, when it came nanorods, hexagonal surface disappeared while cylindrical ones roughened morphology obtained. Secondary measurements showed that exhibited 30.8% reduction relative bare plate aluminium, which provided promising application strategy fabricate desired blocks.
