Nanostructure samples were detained and X-ray diffraction analysis was performed. Samples of nanocomposites with different types of nanocrystallites in selected matrices with decreasing temperature to room temperature were obtained. The influence of the magnetic field on the growth of nanocrystallites has been studied. X-ray diffraction studies to demonstrate the fundamental possibility of KDP crystallite formation in porous Al2O3 matrices. Samples of crystalline nanocomposites with tailored anisotropy in nanoporous Al2O3 matrices were obtained. The morphology of their surface, as well as structural features using a scanning electron microscope were studied. The absorption (transmission) spectra in the optical range at room temperature are studied. The parameters from the optical spectra are calculated. Preparation for studies of the electrical conductivity of a matrix with embedded nanocrystallites was performed. The functional scheme of the experiment on electrical conductivity measurement is offered. The frequency dependence of the lateral resistance for a number of samples based on nanoporous matrices was studied. The possibilities of computer analysis of electron microscopic images of the studied samples using the NIVisionAssistant automated image processing module, which is part of the LabVIEW engineering environment, are analyzed.The luminescence spectra of the basic nanoporous matrices and fabricated crystalline nanocomposites at excitation wavelengths of 250 and 310 nm were studied. For the base matrix, it is shown that a higher quantum yield is achieved by excitation with a wavelength of 310 nm, while the spectral profile is preserved. The main photoluminescence band of the nanocomposite was found to have Product Description popup.authors Adamiv Volodymyr T Karbovnyk Ivan D Klym Halyna I popup.nrat_date 2021-03-23 Close
