Abstract
We report the synthesis of various shaped silver nanoparticles mediated by ZnCl2salt. It has beendemonstrated that the salt, PVP/AgNO3 mole ratio and the type of polyol (EG, DEG, GL) significantly determined twinning probability which is an index of silver seed growth origin. High twining probability arising from low PVP/Ag+ ratio and 50 mole% salt favors 1D grown nanowires and nanorods whereas low twinned amidst high mole% salt (150) in DEG offered 2D grown nanoflakes and nanosheets. Other shaped silver nanoparticles have been found. Accidentally, we arrived at a core shell heterostructure of AgZnOnanocomposite with Ag core enrichment when mole% of the salt was made up to 300. Growth kinetic of nanosphere obtained was monitored and effect of salt mediation was found crucial. Structural evolution of shaped Ag nanoparticles and the nanocomposite have been monitored using XRD, SEM, EDX, TEM and UV/vis.
