Determination of third-order nonlinear optical properties of ABI derivatives
(International Frequency Sensor Association, 2019)
In this paper we studied linear and nonlinear optical properties of novel organic materials MeSBI and MeOBI in form of solution with chloroform as solvent. For experimental measurements we implemented Z-scan method as it ...
Energy level determination of purine containing blue light emitting organic compounds
(SPIE - International Society for Optics and Photonics, 2018)
Organic light emitting diodes (OLED) have found their applications in the mobile and TV screens. Till now the commercially available diodes are made by expensive thermal evaporation in a vacuum. The costs of OLED fabrication ...
Fabrication and characterization of magnetic FePt nanoparticles prepared by extraction–pyrolysis method
(Lietuvos Mokslu Akademijos, 2018)
In the present work, possibilities of the extraction–pyrolysis method (EPM) to produce FePt nanoparticles with the face-centered tetragonal (fct) phase were studied. A mixture of fine-disperse powder of carbonyl iron and ...
Structural, magnetic, dielectric and mechanical properties of (Ba,Sr) MnO3 ceramics
(Elsevier Ltd, 2017)
Ceramic samples, produced by conventional sintering method in ambient air, 6H-SrMnO3 (6H-SMO), 15R-BaMnO3 (15R-BMO), 4H-Ba0.5Sr0.5MnO3 (4H-BSMO) were studied. In the XRD measurements for SMO the new anomalies of the lattice ...
All-organic electro-optic waveguide modulator comprising SU-8 and nonlinear optical polymer
(OSA - The Optical Society, 2017)
In this paper we describe the principles of operation as well as the fabrication and testing steps of an all-organic waveguide modulator. The modulator comprises an SU-8 core and an electro-optic host-guest polymer cladding. ...

Simulation of Young's moduli for hexagonal ZnO [0 0 0 1]-oriented nanowires: first principles and molecular mechanical calculations
(IOP Publishing, 2017)
Morphologically reproducible wurtzite-structured zinc oxide nanowires (ZnO NWs) can be synthesized by different methods. Since ZnO NWs have been found to possess piezoelectricity, a comprehensive study of their mechanical ...
Thin film organic thermoelectric generator based on tetrathiotetracene
(Wiley-VCH Verlag, 2017)
Thin films of p- and n- type organic semiconductors for thermo-electrical (TE) applications are produced by doping of tetrathiotetracene (TTT). To obtain p-type material TTT is doped with iodine during vacuum deposition ...
Orientation of the electric field gradient and ellipticity of the magnetic cycloid in multiferroic BiFeO3
(Taylor and Francis Ltd., 2017)
The paper deals with the hyperfine interactions observed on the 57Fe nucleus in multiferroic BiFeO3 by means of the 14.41-keV resonant transition in 57Fe and for transmission geometry applied to the random powder sample. ...
Multimode time-dependent gyrotron equations for different time scales
(American Institute of Physics Inc., 2017)
Development of gyrotrons requires careful understanding of different regimes of gyrotron oscillations. For a long time, the gyrotron theory was developed assuming that the transit time of electrons through the interaction ...
