Abstract

Electrophoretic deposition from mixtures of CdSe and γ-Fe 2O3 nanocrystals forms identical films on the positive and negative electrodes composed of both types of nanocrystals. In contrast, the electrophoretic deposition from mixtures of CdSe and Au nanocrystals forms films composed of only CdSe nanocrystals, and these films form only on the positive electrode. As the density of charged Au dots is decreased below that of charged CdSe dots, the suppression of CdSe dot film formation on the negative electrode lessens, and films composed of CdSe nanocrystals form on both electrodes.
