Abstract
Results of a study of the electronic structure and optical properties of a novel material based on thin films comprised of Mo nanoclusters obtained by gas-phase magnetron sputtering are presented. The chemical composition of the obtained films immediately after deposition (in situ) and upon exposure to the atmosphere (ex situ) was investigated by X-ray photoelectron spectroscopy. It is shown that exposure to the atmosphere leads to “core–shell” oxidation of the nanoclusters the obtained films are composed of and changes in the valence band. The change in the electronic structure of the obtained films was investigated by spectro-scopy of the characteristic energy losses of electrons. The optical properties of the obtained films were investigated in the wavelength range of 185–800 nm. The possibility of creating thin-film photodetectors based on the obtained Mo nanocluster films for detecting isomeric nuclear transition decay in 229Th nuclei is discussed.
