Abstract ZnO, Zn 0.97 Gd 0.03 O and Ho were prepared via a citrate auto-combustion method. X-ray diffraction (XRD) demonstrated that the investigated nanoparticles in hexagonal structure, with crystallite sizes averaging between 12 60 nm. The morphology of samples is illustrated by field emission scanning electron microscope (FESEM) images. paramagnetic behavior VSM. value optical band gap (E g...

Abstract Novel crystalline and thermally stable chitosan-N-acetylisatin (Chs-NAI) polymer derivatives were synthesized by chitosan modification. These polymers formed insertion of β-cyclodextrin (βCD) doping with zinc oxide nanoparticles (ZnO NPs) yielding pseudopolyrotaxane (Chs-NAI/βCD), Chs-NAI/ZnO-NPs, Chs-NAI/βCD/ZnO NP composites. The chemical structure morphology the newly prepared inves...

In the continuing attempt to find an alternative to CdS windows for CIS absorbers, recent results show that a Cd-doped CIGS surface can produce a cell comparable to the best CdS/CIGS cells. We extend this work to include CIGSSbased cells utilizing the same absorber preparation process as is currently used to manufacture commercial photovoltaic modules. We use current-voltage, quantum efficiency...

The title compound, dizinc cadmium hydroxide tetraoxido-vanadate, Zn(1.86)Cd(0.14)(OH)VO(4), was prepared under low-temperature hydro-thermal conditions. It is isostructural with Zn(2)(OH)VO(4) and Cu(2)(OH)VO(4). In the crystal structure, chains of edge-sharing [ZnO(6)] octahedra are inter-connected by VO(4) tetra-hedra (site symmetries of both V atoms and their coordination polyhedra are .m.)...

A method for the formation of a low-temperature hybrid gate dielectric for high-performance, top-gate ZnO nanowire transistors is reported. The hybrid gate dielectric consists of a self-assembled monolayer (SAM) and an aluminum oxide layer. The thin aluminum oxide layer forms naturally and spontaneously when the aluminum gate electrode is deposited by thermal evaporation onto the SAM-covered Zn...

ZnO nanoparticles were fabricated in sapphire (α-Al(2)O(3) single crystal) by Zn ion implantation (48 keV) at an ion fluence of 1 × 10(17) cm(-2) and subsequent thermal annealing in a flowing oxygen atmosphere. Transmission electron microscopy (TEM) analysis revealed that metallic Zn nanoparticles of 3-10 nm in dimensions formed in the as-implanted sample and that ZnO nanoparticles of 10-12 nm ...

The analysis of the problem of conjunction of information and communication technologies (ICT) with packaging industry and food production was made. The perspective of combining the latest advances of nanotechnology, including nanophotonics, and ICT for creating modern smart packaging was shown. There were investigated luminescent films with zinc oxide nanoparticles, which change luminescence i...

Structural and optical properties of ZnO1-хSх (0 ≤ x ≤ 1.0) thin films grown onto sapphire substrates (с-Al2O3) at 300 C by radio frequency (rf) magnetron sputtering of ZnS ceramic target are studied. A possibility of purposeful controlling sulfur content and, as consequence, ZnO1-хSх band gap energy via changing the ratio of the partial pressures of argon and oxygen are revealed. Linear depen...
