In this paper, thin films based on tin dioxide containing hierarchical structures were synthesized. The process of “growing” these structures was carried out by introducing ammonium hydroxide into the composition of the initial film-forming solutions. The shape and volume of the hierarchical structures were regulated by the amount of introduced ammonium hydroxide. The optical properties of the obtained samples were also studied for further use as transparent conductive coatings. The films were applied using spray pyrolysis. During mapping, it was found that the greatest accumulation of tin was observed along the contour of the structures. Whereas oxygen and chlorine were distributed relatively uniformly over the surface of the samples. Elemental analysis of the samples showed that in all samples the ratio of elements was as follows: Sn>O2>Cl2. The highest tin content was in the sample synthesized from the initial solution containing 0.8 ml of ammonium hydroxide. To determine the effect of the content of hierarchical structures on the optical properties, transmission spectra of the synthesized samples were recorded. The analysis of the results showed that with an increase in the addition of ammonium hydroxide in the composition of the initial solution, the transmittance of the samples decreases, but not critically. They still remain optically transparent.
