Centimetre scale assembly of vertically aligned and close packed semiconductor nanorods from solution

摘要

Assembly of CdS nanorods (8 × 100 nm) into vertically aligned arrays over very large areas on a substrate either as a monolayer or several multilayers is shown by electrophoresis.rnColloidal synthesis of semiconductor nanorods and their subsequent organisation into vertically aligned and close packed monolayers has attracted significant research interest. In such assemblies, the inherent shape and length dependent properties of discrete nanorods such as linear polarised emission and total photon absorption can be collectively harnessed for scalable application as light emitting diodes or low-cost nanorod based solar cells.
