Parallel assembly of CdS nanowires by blade-assisted method

Herein, we demonstrate a new method for parallel depositing CdS nanowires (NWs) on the large-scale substrate with a high deposition yield. The method is based on blade-coating. First, CdS NWs solution is dripped onto the substrate surface. Second, before the CdS NWs solution evaporates, the blade slides along the substrate surface to assemble the CdS nanowires. The mechanism involving ordered alignment of nanowires on the substrate surface was investigated based on the experimental result. This simple approach can be served as a general approach to fabricate the nanowires film.
