The book entitled Novel Synthesis of Fe doped Zinc Oxide Nano particles and Properties deals with ZnO based Diluted magnetic semiconductors (DMS) and magnetic properties of DMS materials seem to be very sensitive to the preparation methods and the structure of materials. This novel surfactant assisted combustion synthesis method is useful in successfully doping Fe in ZnO nanoparticles and as a function of doping concentrations. The crystallite sizes decreased with increase in the Fe concentration. The optical band gaps were found to increase with the increase in doping concentrations which…mehr

Produktbeschreibung
The book entitled Novel Synthesis of Fe doped Zinc Oxide Nano particles and Properties deals with ZnO based Diluted magnetic semiconductors (DMS) and magnetic properties of DMS materials seem to be very sensitive to the preparation methods and the structure of materials. This novel surfactant assisted combustion synthesis method is useful in successfully doping Fe in ZnO nanoparticles and as a function of doping concentrations. The crystallite sizes decreased with increase in the Fe concentration. The optical band gaps were found to increase with the increase in doping concentrations which clearly indicates the blue shift. From ESR studies it is concluded that doped ZnO sample exhibit ferromagnetic in nature which is further confirmed by VSM studies that all the doped sample exhibit ferromagnetic behavior at room temperature. TEM analysis revealed that the obtained nanoparticles are of crystalline in nature with planes confirming wurtzite structure, which is compared with XRD analysis. No secondary phase was identified owing to low doping concentrations of Fe in ZnO nanoparticles.
