Oriented growth of CdS nanoparticulate film with constant average particle size with thickness up to ～ 1 μm

摘要

Oriented growth of hexagonal CdS nanoparticulate film with the C-axis perpendicular to the plane of the surface has been achieved up to a film thickness of ～ 1 μm, using the combination of Langmuir-Blodgett (LB) and chemical bath deposition techniques. This combination is shown to eliminate the inherent limitation of the LB technique on the film thickness (up to ～ 300 A). The average size of the particles has been found to be constant with the film thickness.
