europium (eu) doped zno microsphere based nano-sheets were synthesized through hydrothermal method. effects of different concentrations of europium on structural and optical properties of zno nano-sheets were investigated in detail. prepared un-doped and eu-doped zno samples were characterized using x-ray diffraction (xrd), energy dispersive x-ray spectroscopy (edx), scanning electron microscop...

in current work, cds/black carbon nanocomposites were successfully synthesized with the aid of chestnut and cadmium nitrate as the starting reagents. besides, the effects of preparation parameters such as reaction time, and precursor concentration on the morphology of products and removal of heavy metals (hg+2, pb+2) were studied by scanning electron microscopy images and batch adsorption mode....

Metal organic frameworks (MOFs) of copper and zinc synthesized with 1,4benzenedicarboxylic acid and N,N-dimethylformamide at room temperature and by solvothermal method is reported in this paper. The MOFs were characterized by Fourier transform infrared spectroscopy (FTIR), Scanning electron microscopy (SEM), High resolution transmission electron microscopy (HR-TEM), X-ray diffraction (XRD) and...

Nanoparticles of nickel substituted cobalt ferrite (Nix Co1-xFe2 O4 : 0£ X£ 1) have been synthesized by co-precipitation method. Triton x-100 and oleic acid as surfactants were used. Particles size as estimated by the full width half maximum (FWHM) of the strongest X-ray diffraction (XRD) peak were found 17 and 21nm. Their morphology structure have been determined by scanning electron microscop...

Thin films of copper indium diselenide (CIS) were prepared by chemical bath deposition technique onto glass substrate at 60C. The studies on composition, morphology, optical absorption, electrical conductivity and structure of the films were carried out. Characterization includes X-ray diffraction (XRD), Scanning electron microscopy (SEM), Atomic force microscopy (AFM), Energy dispersive x-ray ...

cuins2 nanostructures were  synthesized  via  a  simple  surfactant-free solvothermal  route.  in  this  synthesis,  thiosemicarbazide  and thioglycolic acid were used as sulfur sources. the effects of different parameters such as type of precursor and time on the morphology and particle  size  of  the  samples  have  been  investigated.  the nanostructures  were  characterized  by  means  of  ...
