Magnon and Phonon Excitations in Nanosized NiO
(Sciendo, 2019)
Single-crystal, microcrystalline and nanocrystalline nickel oxides (NiO) have been studied by Raman spectroscopy. A new band at ~200 cm-1 and TO-LO splitting of the band at 350–650 cm-1 have been found in the spectra ...
Synthesis, structure and spectroscopic properties of luminescent GdVO4:Dy3+ and DyVO4 particles
(Elsevier B.V., 2018)
In this work, we focused on the syntheses, structure and spectroscopic properties of GdVO4:Dy3+ and DyVO4 (nano)particles of different sizes and shapes (spherical nanoparticles of 2 nm, 4 nm, and 20 nm in size, nanorods ...
Synthesis and characterization of GaN/ReS2, ZnS/ReS2 and ZnO/ReS2 core/shell nanowire heterostructures
(Elsevier B.V., 2021)
Layered 2D van der Waals (vdW) materials such as graphene and transition metal dichalcogenides have recently gained a great deal of scientific attention due to their unique properties and prospective applications in various ...
Low temperature structural transformations on the (001) surface of SrTiO 3 single crystals
(American Institute of Physics, 2020)
The smooth (001) surfaces of SrTiO3 (STO) single crystals were investigated by the reflection high-energy electron diffraction method in the temperature range from 5.5 to 300 K. The Raman scattering confirmed the high ...
X-ray absorption and Raman spectroscopy studies of tungstates solid solutions ZncNi1-cWO4 (c=0.0-1.0)
(AIP Publishing, 2020)
The influence of thermal disorder and static distortions on the local structure in microcrystalline solid solutions of tungstates ZncNi1-cWO4 with c = 0.0–1.0 was investigated using temperature-dependent (10–300 K) x-ray ...
Optical properties and structure particularities of LiNbO3 crystals grown from a boron-doped melt
(Taylor and Francis Ltd., 2019)
A series of LiNbO3:B crystals was grown from the melt doped by boron. It is shown that LiNbO3:B crystals possess an increased resistance to optical damage. We have found changes according to Raman spectra confirming the ...
The role of Ga and Bi doping on the local structure of transparent zinc oxide thin films
(Elsevier, 2021-07-25)
Transparent undoped ZnO and additionally doped with Ga and Bi thin films were produced by magnetron sputtering. The thin films were comprehensively characterized by X-ray absorption, X-ray diffraction (XRD), X-ray photoelectron ...
Effects of Pulsed Electric Field on the Physicochemical and Structural Properties of Micellar Casein
(MDPI, 2023)
Pulsed electric field (PEF) as a green processing technology is drawing greater attention due to its eco-friendliness and potential to promote sustainable development goals. In this study, the effects of different electric ...
Ab Initio Study on the Vibrational and Electronic Properties of Radiation-Induced Defects in Potassium Bromide
(MDPI, 2024)
The vibrational and electronic properties of several basic radiation defects in potassium bromide are computed at the quantum mechanical level using a periodic supercell approach based on hybrid functionals, an all-electron ...
