Hierarchical Self-Assembly of Nano- and Microstructures of Zinc Oxide in Combined Sol-Gel Systems

Using the methods of optical spectrometry and IR spectroscopy, the processes of self-assembly of nano- and microstructures of zinc oxide in combined sol-gel systems obtained by mixing film-forming sols with different maturation times were studied. Characteristic bands and absorption peaks in the IR spectra were established, demonstrating an unambiguous relationship between the IR transmittance — radiation and maturation time for different volumetric ratios of mixed sols. It has been shown that experimental IR spectroscopy data correlate with optical spectrometry data in the visible and UV radiation range. The correspondence of ZnO films formed on the basis of combined sol-gel systems to the tasks of nanostructural engineering has been demonstrated.
