The application prospect of zinc oxide (ZnO) nanostructures largely relies on the ability to grow nanoobjects with necessary geometry. In this study well-aligned ZnO nanorod arrays with a high density and uniformity were successfully synthesized on the glass substrates by a hydrothermal method at low-temperature. The aqueous solutions of zinc nitrate hexahydrate and hexamethylenetetramine was used. The effect of seed layer (obtained by electrochemical method and by vacuum deposition method) on the alignment of ZnO nanorods has been investigated. The morphological properties of the ZnO nanorods were also examined in accordance with varying the magnetron sputtering angle for ZnO seeds deposition. It is also shown that the electric field can control the direction of the growth of ZnO nanorods. Morphological, structural and compositional characterizations of obtained films were carried out by scanning electron microscopy, energy-dispersive X-ray spectroscopy and X-ray diffraction analysis methods.
The article examines the processes of second harmonic generation (SHG) when selenium-metal (Cu) film
structures are illuminated by femtosecond radiation (180 fs, 80 MHz) at wavelength 800 - 1000 nm. Selenium-copper
structures were obtained by successive thermal evaporation of selenium and copper onto the glass substrate in vacuum.
Microanalysis of the film composition was performed to determine amount of copper in thin films. The as-evaporated
selenium-copper structures were crystallised by annealing in inert atmosphere at temperature 85°C. Just evaporated as
well as annealed thin films were explored. The experiment was performed by confocal microscope  where the
femtosecond radiation from laser was injected. A photosensitivity of structures in question was then determined as
functions of intensity and wavelength of the incident radiation . Second harmonic intensity dependence on thickness
of Cu layer was also observed. We found out that adding small amount of Cu increases reflected SH intensity.
