In this work, submicro- and nanoparticles of Bi2O3 were synthesized by the method of thermal decomposition of an aerosol containing bismuth nitrate as a precursor on an aluminum substrate. According to atomic force microscopy, the particles have a clearly pronounced crystallographic faceting of a pyramidal shape at the base of which lies a triangle with angles of ∼60° and 120° degrees at one of the vertices, the angle at the apex of the pyramid is ∼90°. The angle of inclination of the plane in the direction of one of the angles - the highest point of the cluster - ranges from 10° to 14°. It was found that the resulting particles have an ordered layered structure, which makes it possible to assume a single-crystal structure. The height of the layers (terraces) reaches 5 nm, the distance between the boundaries of the terraces is up to 30 nm. Individual formations on the surface of the substrate reach a height of 90 nm, while the length of the longest side of the base is up to 600 nm. At the same time, they have education. The data obtained are of interest for further study of the properties of submicro- and nanostructures based on Bi2O3, as well as for the targeted synthesis of new functional materials with an improved complex of electro-physical and optical properties.
