Sodium zinc borate glasses doped with dysprosium and modified different concentrations of barium oxide (0–50 mol %) were fabricated using the melting quenching technique. The structural properties prepared glass systems characterized XRD FTIR methods. absorption spectra measured to determine their energy gap related optical properties. density other physical parameters also reported. Additionally, help Photon Shielding Dosimetry (PSD) software, we investigated radiation shielding at values....
The present paper describes recent developments in the employment of ITO (In2O3:Sn) nanoparticles for preparation transparent conducting coatings and discusses capabilities limits this approach, especially applications display smart window technology. Meanwhile, redispersible ITO, which shows best electrical properties among coating oxides (TCOs), can be produced reproducibly on an industrial scale various products are market.
ZnO nanoparticles (ZnO NPs) were synthesized using hydrothermal and sol-gel techniques zinc acetate dihydrate (Zn (CH3COO)2.2H2O) as a row material methanol solvent. The structural properties of NPs studied EDX, XRD, TEM, the optical characterized UV-VIS PL spectroscopies. showed high purity revealed wurtzite (hexagonal) crystal structure with particle size (D) ranged from 25 nm to 28 nm. absorption spectra samples sensitizing dyes performed. obtained exhibited direct bandgap 3.15 eV....
Abstract Colloidal solutions containing fully redispersed crystalline In2O3:Sn(ITO)nanoparticles with an average size up to 30 nm and adequate organic binders(e.g. hydrolysable silanes)offer new possibilities coat substrates a transparent or antiglare conducting layer by different wet chemical coating techniques. The layers can be processed UV light irradiation at low temperature( < 130°C). process allows any types of which cannot withstand high temperature such as plastics(tested PC, PE,...
Zinc oxide nanoparticles synthesized via simple precipitation method and aged at different time were used as photoanodes of dye sensitized solar cells (DSSCs).The structural the optical properties obtained zinc investigated.The performance assembled was studied efficiency such cell compared a relation aging ZnO nanoparticles.
Abstract ZnO nanoparticles were synthesized using sol gel technique at different calcination temperature. The effect of temperature on the structure and optical properties NPs studied in detail by techniques, X-ray diffraction, high-resolution transmission electron microscope, UV-VIS spectroscopy photoluminescence spectroscopy. diffraction analysis revealed that crystalized a wurtzite estimated average particle size increased from 24.7 to 40.4 nm with increasing In addition, d spacing...
In the present work, ZnO nanoparticles were synthesized via a simple wet chemical (hydrothermal) technique using zinc acetate dihydrate (Zn(CH3COO)2.2H2O) as row material dissolved into absolute methanol and aqueous NaOH precipitation agent. The X-ray diffractometer (XRD) patterns showed standard hexagonal wurtzite structure of NPs with average particle size about 28±2 nm. High resolution-transmission electron microscopy (HR-TEM) micrograph semi-spherical particles an 25.3±6 nm, which agreed...
