Abstract

Composite monolayer films of behenic acid and CdTe nanoparticles capped with either 1-thioglycerol or thioglycolic acid were prepared by the vertical and horizontal deposition methods on mica and graphite substrates. The films were studied with pressure-area isotherms, Fourier transform infrared spectroscopy, atomic force microscopy, UV-vis absorption and photoluminescence spectroscopy. New anisotropic material was assembled at interface of solution in result of interaction between of thioglycolic acid stabilized nanoparticles and monolayer film of behenic acid. The structure of the CdTe/behenic acid assemblies was found to be sensitive to the method of preparation and texture of the substrate. On the graphite surface, CdTe-containing films reorganize into lamellae. Assemblies formed on the mica surface can be reversibly translocated between the substrate and the atomic force microscopy (AFM) tip. © 2002 Elsevier Science B.V. All rights reserved.
