It is shown that the inclusion of Nd3+ cations in the crystalline structure of ZnO changes the morphology of ZnO films from coarse grains to the formation of hexagonal columnar nanostructures. A detailed analysis of photoluminescence and Raman light scattering spectra confirms that Nd3+ cations replace zinc positions in the zinc oxide lattice. According to the results of scanning electron microscopy, the synthesized powders have a conglomerate structure. It was established that the morphology of powder particles primarily depends on the content of Nd3+ in the material. A comparative assessment of the efficiency of the photocatalytic properties of ZnO thin films doped with neodymium (5, 10% by weight) was carried out, depending on the conditions of production. The highest rate of photodegradation of the model dye (63.9% after 6 h of irradiation) is shown by ZnO-Nd films (5 wt.% Nd2O3), deposited during 30 min of magnetron sputtering.
