Hydrochemical deposition of the films of stoichiometric composition Cu2S was determined in ammoniac and acetated layer systems by energy-dispersive elemental analysis. The film composition almost corresponds to formula unit Cu2S. Electron-microscopic research of the film morphology showed that the particles, which are formed the films of Cu2S have average size ~10 nm.
The authors conclude that:
1. Nanocrystal films of copper (I) sulfide with the thickness 100±10 nm exhibiting good adhesion to sitall substrate were obtained by hydrochemical deposition in systems «CuSO4 – NaAc – CS(NH2)2» and «CuSO4 – NH3 – CS(NH2)2». EDX analysis confirmed that at hydrochemical deposition the formation of thin Cu2S film phase which is closed to stoichiometric composition with the average content of metal and sulfur 66.59 and 33.41 at.%, 66.82 and 33.18 at.% in acetated and ammoniac systems correspondingly occurs.
2. Morphology of obtained films Cu2S was studied by electron-microscopic research, their nanocrystal nature was determined.
