Abstract
Using an anodic alumina template as a nanoscale reaction vessel, the authors developed a simple and unique method to prepare highly ordered arrays of nanocrystals in isolated nanowells. The highly ordered arrays of nanoscale wells were fabricated by short anodization. After the nanoscale wells were filled with a precursor solution of NaCl by dewetting, the solvent of the precursor solution was evaporated, resulting in spontaneous formation of uniformly sized NaCl nanocrystals inside the nanoscale wells. The size of crystals could be easily adjusted by varying the concentration of the precursor solution and the size of nanoscale wells. This approach is simple and cost-effective, and it can fabricate nanocrystal arrays on substrates with high throughput. It can also be readily adapted to synthesize other types of high-density nanocrystal arrays on different substrates. © 2015 The Authors
