N2 - The methods of incorporating thiol-stabilized CdTe nanoclusters into mono- and multilayer films produced by the Langmuir-Blodgett (LB) technique on the basis of anionic (behenic acid) and cationic (octadecyltrinonylammonium (ODTNA) iodide) surfactants were investigated. 'Pressure-area' isotherms, quartz crystal microbalance (QCM), FTIR, atomic force microscopy (AFM) and UV/Vis spectroscopy give evidence on the incorporation of the nanoclusters in LB films. The limiting surface area of the behenic acid monolayer increases with a simultaneous decrease of the film strength. The optical absorption of the films obtained through the incorporation of the clusters acquires the features of CdTe nanocrystals. The noticeable difference in the deposition process was observed for the two types of stabilizing ligands (thioglycerol and mercaptoethanol) used for the CdTe clusters. The bonding of the CdTe clusters with the carboxylic group of behenic acid monolayer is established for the thioglycerol-stabilized clusters.
