Doping of Nano Cobalt Ferrites by Cupper: Structural and Magnetic Properties Studies
A series of Cupper-substituted cobalt nano ferrites (CuxCo1-x Fe2O4 with = 0.00, 0.10, 0.20, 0.30 and 0.4) was synthesized via hydrothermal method. The structural characterizations of all the prepared nanoparticles were performed using powder x-ray diffraction, EDAX and FTIR analyses. These studies confirmed the formation of single-phase spinel structure in at lower compositions. The increase in the value of lattice ... Read more

Synthesis, characterization and photocatalysis enhancement of Eu2O3-ZnO mixed oxide nanoparticles
Pure ZnO nanoparticles (NPs) and mixed Eu2O3 and ZnO NPs with different Eu2O3 ratios (5%, 10%, and 15%) were synthesized by a precipitation method under optimum conditions. The synthesized samples were characterized by means of X-ray diffraction, scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy, transmission electron microscopy (TEM), Fourier transform infrared (FTIR) spectroscopy, Raman spectroscopy, and UV–vis diffuse reflectance spectroscopy. ...

Synthesis, photoluminescence and optical constants evaluations of ultralong CdO nanowires prepared by vapor transport method
Ultralong CdO nanowires (NWs) were synthesized on Au coated Si and quartz substrates by using vapor transport method. The synthesis temperature was chosen via thermal gravimetry analysis (TGA) and it was 1150C. The formation of CdO was confirmed by energy dispersive analysis of X-ray (EDAX) and Fourier transform infrared (FT-IR) spectroscopy analysis. The CdO nanowires was found to grow via ... Read more
