New findings directed at improving the spectral properties of inorganic materials in the alkaline-earth metal fluoride group by coating with carbon nanotubes are reported using the example of the optical material MgF2. Modeling and data analysis show that the nanostructures obtained can be used as modern transparent optical elements, including nanostructured protective windows and plane-parallel plates for devices operating in the UV spectral range. The investigated structured magnesium fluoride can be used as a new engineering material for optical-emission and X-ray spectrometers.

The article presents the results of studies of the optical and photocatalytic properties of titanium oxide thin films deposited by cathodic arc deposition in an oxygen-containing atmosphere. It has been shown that thin films with various oxidation degrees are deposited depending on the oxygen flow rate into the operating chamber. Study of the obtained films has shown that the films obtained in the transition mode between the deposition of Ti metal films and TiO2 dielectric films have the maximum photocatalytic activity. This deposition mode is observed when the oxygen flow rate into the operating chamber is from 9 to 12 cm3/min.
