Abstract:
This work is devoted to the study of the efficiency of using the effect of nickel doping of thin films based on
CdSe with the possibility of varying the structural and optical properties due to a change in the phase composition
of the films. The method of electrochemical reduction of metal ions from aqueous solutions of electrolytes was
chosen as a method for obtaining films. The variation of the applied potential difference was used to produce films
with different characteristics. To characterize the properties and dynamics of their changes, methods of atomic
force microscopy, energy dispersion analysis and X-ray diffraction were chosen. The strength mechanical
properties of the films were studied using the indentation method. During experiments conducted dependencies of
changes of structural, optical, strength characteristics of synthesized films depending on production conditions
are obtained. Photocatalytic tests to determine the rate and efficiency of decomposition of the Rodamine B
organic dye showed that films in the composition of which the NiSe phase prevails have the greatest potential for
use as photocatalysts.
