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.
Results of second harmonic (SH) generation in amorphous and crystalline selenium films induced by titanium-sapphire
femtosecond laser (wavelength λ - 800-1000 nm) are presented. It is found that the highest intensity of SH is provided by
fundamental wave at wavelength 1000 nm and it reaches maximum in approximately 100 sec. The intensity of transmitted SH depends on film thickness while that of reflected does not.
We have performed the investigation of dot matrix holographic recording in amorphous As<sub>2</sub>S<sub>3</sub> chalcogenide films
with different thickness on Al coated glass substrates. The control over the interference minimum of reflection during the
evaporation process allowed obtaining As<sub>2</sub>S<sub>3</sub>-Al system with a minimum value of initial reflection in defined spectral
region. The investigation of dependence of diffraction efficiency of holographic recording on both film thickness and
initial conditions of reflectivity in the system was performed. The main advantage of this type of system is the possibility
to increase optical sensitivity of material in predefined spectrum region for phase hologram recording.
