Changes in structure and conduction type upon addition of Ir to ZnO thin films
(Elsevier B.V., 2017)
Zn-Ir-O (Zn/Ir ≈ 1/1) thin films have been reported to be a potential p-type TCO material. It is, however, unknown whether it is possible to achieve p-type conductivity at low Ir content, and how the type and the magnitude ...
Analysis of the U L3-edge X-ray absorption spectra in UO2 using molecular dynamics simulations
(Elsevier Ltd, 2017)
Uranium L3-edge X-ray absorption spectroscopy was used to study the atomic structure of uranium dioxide (UO2). The extended X-ray absorption fine structure (EXAFS) was interpreted within the ab initio multiple-scattering ...
Determination of Kerr and two-photon absorption coefficients of indandione derivatives
(SPIE, 2017)
We studied nonlinear optical properties of two different aminobenziliden-1,3-indandione derivatives - DDMABI and DMABI-OH by employing the Z-scan method. Through this we described how different donor and acceptor groups ...
A comparative study of heterostructured CuO/CuWO4 nanowires and thin films
(Elsevier B.V., 2017)
A comparative study of heterostructured CuO/CuWO4 core/shell nanowires and double-layer thin films was performed through X-ray diffraction, confocal micro-Raman spectroscopy and electron (SEM and TEM) microscopies. The ...
Stimulated emission and optical properties of pyranyliden fragment containing compounds in PVK matrix
(Elsevier Ltd, 2017)
Organic solid state lasers are thoughtfully investigated due to their potential applications in communication, sensors, biomedicine, etc. Low amplified spontaneous emission (ASE) excitation threshold value is essential for ...
Synthesis and characterization of ZnO/ZnS/MoS2 core-shell nanowires
(Elsevier B.V., 2017)
Hybrid nanostructures composed of layered materials have recently attracted a lot of attention due to their promising electronic and catalytic properties. In this study, we describe a novel synthesis strategy of ZnO/ZnS/MoS2 ...
Donor and acceptor substituted triphenylamines exhibiting bipolar charge-transporting and NLO properties
(Elsevier Ltd, 2017)
Donor-acceptor type triphenylamine-based malonodinitriles were synthesized and their thermal, optical, photophysical, electrochemical and nonlinear optical properties were studied. The synthesized compounds formed glasses ...
Unveiling Molecular Changes in Water by Small Luminescent Nanoparticles
(Wiley-VCH Verlag, 2017)
Nowadays a large variety of applications are based on solid nanoparticles dispersed in liquids—so called nanofluids. The interaction between the fluid and the nanoparticles plays a decisive role in the physical properties ...
Tunneling luminescence in long lasting afterglow of SrAl2O4:Eu,Dy
(Elsevier B.V., 2017)
A long lasting (afterglowing) luminescent material SrAl2O4: Eu2+, Dy3+ was prepared by high temperature solid-state reaction method. The processes responsible for long lasting luminescence were studied by means of luminescence ...
Luminescence and Raman Detection of Molecular Cl2 and ClClO Molecules in Amorphous SiO2 Matrix
(American Chemical Society, 2017)
Chlorine is a common undesirable impurity in synthetic SiO2 glass for ultraviolet optics and optical fibers. It is usually incorporated into glass as bound Si-Cl groups or interstitial Cl2 molecules. We report a high-sensitivity ...
