Gallium-doped zinc oxide nanopowders with high electrical conductivity were prepared by calcining the precursor synthesized from ZnSO4·7H2O, GaCl3 and NH4HCO3 by co-precipitation method. The obtained samples were characterized by FE-SEM, TEM, XRD, XPS and BET techniques. The precursor particles were in the shape of sheet-like with size about several hundred nanometers. The electrically conductive zinc oxide particles, in the shape of sphere-like, were about 10~40 nm with low agglomeration, and the specific surface area was 28.7 m2/g. XRD and XPS results showed that all the doped Ga exists as the substitution form of Ga• Zn in the ZnO system. The volume resistivity of the product was as lower as 4.5 :·cm.

In through concoction co-precipitation strategy using ferric nitrate, zinc nitrate and sodium hydroxide in fluid arrangements, orchestrate and portrayal of Fe doped ZnO nanoparticles were prepared in the present work. X-beam diffraction has confirmed the growth of Fe doped ZnO from the precursor. This result has revealed that nanoparticles have integrated excellent crystalline forces in nature. SEM investigations show that ZnO nanoparticles have been doped by the round and minimally agglomerated Fe. Room temperature powerless ferromagnetism, distinctive in the appealing characteristics of Fe doped ZnO powderKeywords in relation to room temperature: zinc oxide, SEM, chemical precipitation, XRD, VSM

Nanotechnology is a field of applied science focused on design, synthesis and characterization of nanomaterials. The nickel and magnesium have improved their applications in transparent electrodes and nano electronics. In addition, magnesium oxide has moisture resistance and high melting point properties. In the present work has been carried out in the development of green crystalline powder of nickel doped magnesium oxide nanoparticles by Co-precipitation method, from the mixture of nickel chloride and magnesium chloride with KOH as solvent. From the XRD results, crystalline size of the particle can be observed. Spherical structure of Ni doped MgO nanoparticles were indicated by SEM results and powdered composition of samples were obtained from FTIR. EDAX represents the peak composition of the nanoparticle. The above analytical techniques have confirmed that the Ni doped MgO nanoparticles obtained from the mixture of NiCl2 and MgCl2.
