Electrophoretic Deposition of Cadmium Sulfide Nanoparticles: Electric Field and Particle Size Effects

Abstract:

The present work shows the electric field and particle size effects on the formation of nanostructured arrays by electrophoretic deposition of cadmium sulfide (CdS) nanoparticles. The CdS nanoparticles with mean diameter below 6 nm were prepared by a microwave assisted synthesis. These nanoparticles were aged for one and two weeks at room temperature in order to produce nanoparticle agglomeration. The CdS nanoparticles were deposited on aluminum plates, with 1 cm of distance between them, using a constant applied voltage of 600 and 900 mV for 1 min. The nanostructures formed using CdS nanoparticles freshly prepared under 900 mV show spherical morphology. Under a voltage of 600 mV, nanostructures with elongated morphology were obtained.
