Abstract:

The mechanism of hydrolytic decomposition of thiocarbamide upon the interaction with metal salts with deposition of thin films of sulfide was proposed. The kinetic studies of the transformation of metal salt into sulfide and IR spectroscopy confirmed that one of the hydrolysis products of thiocarbamide was cyanamide. The concept about the activation of thiocarbamide decomposition was extended due to the nucleophilic addition of anions to form an intermediate reaction complex thiocarbamide metal ion nucleophile. The activation weakens in the order OH- > CH3COO- > Cl- > Br- > I-. The presence and active role of colloidal components of reaction mixtures in the nucleation and formation of films of metal sulfides by chemical bath synthesis were established by spectrophotometric and kinetic measurements. It was concluded that from the viewpoint of fractal formalism metal sulfide films are formed in chemical bath deposition via the mechanism of cluster cluster aggregation in the form of consecutive evolution of structural levels. A complex scheme of the mechanism of chemical bath deposition of metal sulfides by thiocarbamide was proposed. The results of studies of their phase composition, microstructure, and properties are presented.
