SYNTHESIS AND CHARACTERIZATION OF NICKEL DOPED ZINC OXIDE NANOPARTICLES BY SOL ? GEL METHOD

Zinc Oxide (ZnO) referred to as II ? VI semiconductor because Znic belong to the second group and oxygen belongs to the sixth group of the periodic table. As grown ZnO in n ? type semiconductor and its n ? type conductivity can be controlled by growing it in an oxygen deficient atmosphere or by doping it with group III element like Al, Ga, or In. High quality 3d doped ZnO samples were required to synthesize a functional DMS (diluted magnetic semiconductor) whose magnetic properties were controlled by changing the carrier concentration, which Implies that there was a need to investigate the transport properties of (TM) ion doped ZnO. Hence the optical properties of undoped and TM ion Ni doped ZnO sample had been investigated and the valence state of these doped had been conformed through optical studies. The chemical synthesis of semiconductor nanoparticles from (~1 ? 20nm) in diameter with short ? range structure were essentially the same as the bulk semiconductor.
