Nanocomposites of transparent multilayer structures of ZrO@sub 2@/polymer thin-films have been fabricated on silicon and quartz substrates utilizing the Ionic Self-Assembled Monolayer (ISAM) method. This method is based on the alternating adsorption of anionic and cationic polyelectrolytes in the aqueous forms. The deposition process was monitored by UV/Vis spectroscopy and ellipsometry. A linear behavior of both optical absorption and film thickness as the number of bilayers increases was observed, which indicated the formation of homogeneous and uniform thin-films on both substrates. The study also showed the control of film thickness by changing the ZrO@sub 2@ concentrations. It was observed that the thickness of each bilayer of the thin-films increased with the ZrO@sub 2@ concentration. For the films with ZrO@sub 2@ concentrations of 10 and 30 mg/ml, the thickness of each adsorbed bilayer were 18 and 24 Ångstroms, respectively.
