Abstract

ZnO nanocomposites have been synthesized by co-precipitation method and studied the role and effect of amino groups containing organic reagents such as ethylenediamine (en), triethylamine (tea) and octadecylamine (oda) etc. with different precipitating agents , on its morphology. The samples were characterized by X-ray diffraction and scanning electron microscopy. The organic layer can be chemisorb or physisorb onto surface atoms, preventing further growth of the nanoparticles during synthesis and avoiding aggregation. The ligands interact with the surface through amine functional groups via noncovalent and hydrogen bonding. They not only passivate the surface but also influence the solubility and stability of the nanocrystals.
