The results of studying the morphology and optical properties of copper and fluorine-doped ceramic TiO 2 films synthesized using electrolytic and solvothermal methods are presented. It is shown that the films obtained consist of oriented arrays of nanotubes with anatase crystal structure, narrow size distribution, and a high degree of hexagonal self-organization. The influence of the conditions of the solvothermal process on the composition, morphology, structure, and optical properties of the materials obtained has been established.
