| Abstract: | The method for preparation of the composite films based on a silver organosol (14 nm, 0.02 M) stabilized by sodium bis(2-ethylhexyl) sulfosuccinate in n-decane has been proposed. The approach has been based on the uniform deposition of the organosol onto the glass substrate using the spin-coating technique. The relative centrifugal force value is changed from 0.1 to 280×g. Uniform, hydrophilic films exhibiting a surface plasmon resonance (SPR) signal have been obtained. An increase in the organosol volume from 10 to 50 µL makes it possible to affect the surface, mechanical, and optical properties of the obtained films. The root-mean-square roughness, Young's modulus, and SPR signal intensity change from 6 ± 2 to 38 ± 20 nm, from 24.2 ± 0.5 to 131 ± 8 kPa, and from 0.06 to 0.14, respectively. The proposed method has made it possible to use various organosols of metals and their compounds (e.g., gold, iron oxides, etc.) for the preparation of films with promising functional optical and magnetic properties.
