Luminescence characteristics of magnesium aluminate spinel crystals of different stoichiometry
(Institute of Physics Publishing, 2019)
Magnesium aluminate spinel single crystals with different stoichiometry, MgAl2O4 (1:1 spinel) and MgO 2.5Al2O3 (1:2.5) were investigated using different optical methods (cathode-, photo- and thermally stimulated luminescence ...
Investigation of photoluminescence and amplified spontaneous emission properties of cyanoacetic acid derivative (KTB) in PVK amorphous thin films
(SPIE, 2018)
In this work photoluminescence and amplified spontaneous emission properties of new original 2-cyanoacetic acid derivative in different concentration mixed in polyvinyl carbazole (PVK) matrix were investigated. Ethyl ...
Mass recovery of carbonated fabrics of glass fibres after isothermal heating
(Institute of Physics Publishing, 2019)
Leaching of Na+ ions in sodium oxide (Na2O) and silica (SiO2) containing glass is well investigated mainly due to its weak weathering. The object of this study was naturally (at room conditions) leached, steady state product ...
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 ...
Electronic processes in doped ZnO nanopowders
(Institute of Physics Publishing, 2019)
ZnO nanocrystals, undoped and doped with Iridium or Indium were prepared by solar irradiation in Heliotron reactor in PROMES CNRS facilities, France. The comparative analysis of the excitonic spectra of ZnO single crystal ...
Determination of Kerr and two-photon absorption coefficients of ABI thin films
(SPIE, 2018)
In this paper we report the results of studied nonlinear optical properties of DMABI-Ph6 in form of solutions with chloroform as solvent and guest-host thin films with poly(methyl methacrylate) as host material. We implemented ...
Electro-catalytic and photo-catalytic reformation of CO2–reactions and efficiencies processes (Review)
(Institute of Physics Publishing, 2019)
Energy harvesting with lowest environmental impact is one of key elements for cleaner future. Photocatalytic as well as electrocatalytic CO2 reformation processes are considered as prominent methods. Thus, extensive research ...
First principles evaluation on photocatalytic suitability of 2H structured and [0001] oriented WS2 nanosheets and nanotubes
(Institute of Physics Publishing, 2019)
Pristine WS2 multilayer nanosheets (NSs), which thickness h NS varies from 1 to 12 monolayers (MLs), as well as single- and multi-walled nanotubes (SW and MW NTs) of different chirality, which diameter d NT exceeds 1.9 nm, ...
Luminescence of F2 and F3 + centres in LiF crystals irradiated with 12 MeV 12C ions
(Institute of Physics Publishing, 2018)
Dependences of the nanohardness and photoluminescence of F 2 and F 3 + centers on the depth in LiF crystals irradiated with 12 MeV 12 C ions to fluences 10 10 -10 15 ions/cm 2 were studied using laser scanning confocal ...
Different approaches in sulfonated poly (ether ether ketone) conductivity measurements
(Institute of Physics Publishing, 2019)
Ion conductivity of sulfonated poly (ether ether ketone) (SPEEK) membranes with various degree of sulfonation (DS) was investigated using impedance analysis with different measuring cell configuration and ion conductivity ...
