Paramagnetism of cobalt-doped ZnO nanoparticles obtained by microwave solvothermal synthesis
Zinc oxide nanopowders doped with 1-15 mol % cobalt were produced by the microwave solvothermal synthesis (MSS) technique. The obtained nanoparticles were annealed at 800 °C in nitrogen (99.999%) and in synthetic air. The material nanostructure was investigated by means of the following techniques: X-ray diffraction (XRD), helium pycnometry density, specific surface area (SSA), inductively coup...
متن کاملMicrowave solvothermal synthesis and characterization of manganese-doped ZnO nanoparticles
Mn-doped zinc oxide nanoparticles were prepared by using the microwave solvothermal synthesis (MSS) technique. The nanoparticles were produced from a solution of zinc acetate dihydrate and manganese(II) acetate tetrahydrate using ethylene glycol as solvent. The content of Mn(2+) in Zn1- x Mn x O ranged from 1 to 25 mol %. The following properties of the nanostructures were investigated: skeleto...
متن کاملRoom Temperature Ferromagnetism in Cobalt Doped ZnO Nanoparticles
In this work we report synthesis and magnetic characterization of cobalt doped ZnO nanoparticles (with different percent of doped cobalt oxide). Synthesis of the materials was carried out at room temperature by polyacrylamide-gel method, using zink sulfate and cobalt nitrate as source materials, acrylamide as monomer and N,N-methylene bisacrylamide as a lattice reagent. Characterization of the ...

متن کاملSolution-based synthesis of cobalt-doped ZnO thin films
Undoped and cobalt-doped (1-4 wt%) ZnO polycrystalline, thin films have been fabricated on quartz substrates using sequential spin-casting and annealing of simple salt solutions. X-ray diffraction (XRD) reveals a wurzite ZnO crystalline structure with high-resolution transmission electron microscopy showing lattice planes of separation 0.26 nm, characteristic of (002) planes. The Co appears to ...
