Close-packed cubic copper ferrites (CuFe2O4) nanoparticles were synthesized using an effective thermal-treatment method directly from aqueous solution containing and iron nitrates as metal precursors poly(vinyl pyrrolidone) a capping agent. The FTIR spectra of the calcined samples revealed vibration bands Fe–O Cu–O at 315 535 nm respectively. structural, morphological, optical magnetic properties nanocrystal powder analyzed various characterization techniques. X-ray diffraction unveiled...
A facile thermal-treatment route was successfully used to synthesize ZnO nanosheets. Morphological, structural, and optical properties of obtained nanoparticles at different calcination temperatures were studied using various techniques. The FTIR, XRD, EDX, SEM TEM images confirmed the formation nanosheets through in temperature between 500 650°C. showed a morphological structure nanosheets, which inclined crumble higher temperatures. XRD FTIR spectra revealed that samples amorphous 30°C but...
The present study reports the structural and magnetic characterization of spinel zinc chromite (ZnCr 2 O 4 ) nanocrystallines synthesized by thermal treatment method. samples were calcined at different temperatures in range 773 to 973 K. Polyvinylpyrrolidone was used control agglomeration nanoparticles. average particle size nanocrystals determined powder X‐ray diffraction which shows that crystallite increases from 19 nm K 24 result good agreement with transmission electron microscopy...
The particle size, morphology, and stability of Ag-NPs were investigated in the present study. A Q-Switched Nd: YAG pulsed laser (λ = 532 nm, 360 mJ/pulse) was used for ablation a pure Ag plate 30 min to prepare organic compound such as ethylene glycol (EG) biopolymer chitosan. media (EG, chitosan) permitted making NPs with well dispersed average size EG is about 22 nm chitosan 10 spherical form. Particle compared distilled water reference. samples studied by measuring UV-visible absorption...
Zinc oxide nanoparticles were synthesized by the thermal-treatment method. Polyvinyl pyrrolidone was used as capping agent and nitrate a precursor. The samples calcined at 500 550°C for removal of organic compounds. structural characteristics examined X-ray diffraction transmission electron microscopy. results show that average particle size increases with increase in calcination temperature. optical properties characterized room temperature using UV–Vis spectrophotometer wavelength range...
In the present study, gold nanoparticles were synthesized in various polymer solutions by means of employing laser ablation technique at same time. Specifically, polyethylene glycol and chitosan solutions, order to compare effects liquid media which served as stabilizers for particle size volume fraction nanoparticles. addition, this experiment was repeated distilled water reference purposes. As findings indicated, obtained about 7.49 nm, that is, smaller than those solution water,...
Cadmium oxide (CdO) nanoparticles was synthesized from an aqueous solution containing metal nitrate as a precursor and polyvinyl pyrrolidone (PVP) capping agent by simple thermal-treatment method. The as-synthesized sample has been calcined at various temperatures 500 to 650 °C remove the organic matters. structure morphology of have examined X-ray diffraction (XRD) transmission electron microscopy (TEM), respectively. results obtained supports fact that thermal treatment method utilized for...
