Cu and Fe doped cadmium sulfide nanoparticles were prepared with a wet chemical synthesis by mixing the reactants in double distilled water solvent. Thioglycerol (TG) was employed as the capping agent and also the reaction catalyst. The estimated particle size of prepared samples was found in the range 3-4 nm. Properties of particles were investigated using photoluminescence spectroscopy (PL) and...
Various loading amount of La-CuO/TiO2 were synthesized via a one step sol-gel process. The crystal structure and chemical properties were characterized using X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS). XRD analysis revealed that two characteristic peaks at 35.54° and 38.76° according to cubic CuO were observed in the X-ray diffraction patterns of La-CuO/TiO2. Ti4+, Olat into...
Mg1-xFexB2 superconductor was prepared by in situ solid state reaction to study the effects of nano-iron doping on the superconductivity of MgB2. Two kinds of nano-iron sources were used: nano-iron particles and nano-iron wires. It was found that crystal structure was not affected by nano-iron doping for either form of dopant source. Tc, Jc, and Hirr were severely suppressed by iron nano-particles...
Nd3+ doped PbZr0.52Ti0.48O3 (PNZT) nanopowders were prepared by sol-gel methods in ethylene glycol system. Neodymium nitrate was used as Nd3+ source. The reaction mechanisms of nanopowder preparing process from the sol were discussed through using FTIR, XRD, TG-DTA, and it was proved that the heating temperature of PNZT was 50degC-100degC higher than PZT. PNZT lattice structure was characterized...
