Hydrochemical Deposition of Cu2S Films Using Thiocarbamide

Abstract

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 European Reviews of Chemical Research, 2016, Vol. (7), Is. 1 5 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.
