Abstract
Herein we report metal nanoparticle directed growth of assembled zinc oxide nanostructures by a facile solution phase route. Si substrates with silver nanoparticles are subjected to low temperature hydrothermal growth. Coulombic attraction resulted in migration of Zn growth species onto Ag nanoparticle surface. SEM analysis revealed preferential nucleation and growth of zinc oxide nanostructures on Ag nanoparticles. Longer reaction period lead to formation of mulberry like assembled ZnO nanostructures. XRD analysis confirmed growth of zinc oxide nanostructures. The formed ZnO nanostructures exhibit well defined band edge PL peak corresponding to excitonic recombination.
