Surface Stabilised Quantum Confined ZnO Nanosystems

We synthesized the ZnO doped with Mg2+, Cu2+ and Ag+ nanosystems by employing polyvinyl alcohol (PVA), PVP and biotin as organic capping agents by chemical co-precipitation route. All the synthesized materials were characterized by X-ray diffraction for structural analysis and some of the synthesized materials by scanning electron microscopy for the surface morphological analysis. Furthermore we have observed that the surface passivation will lead to structural and size stability of the nanosystems. It was also observed that all the organic polymers employed in the synthesis process have the same effect on the crystallite sizes and will be able to stabilize against growth and agglomeration of the nanoparticles. Controlled synthesis of the nanoparticles leads to the beautiful flakes like morphology.
