Abstract
This work reports on the fragmentation of rod-shaped ZnO nanostructures into spherical nanoparticles under 120MeV Ag9+ swift ion irradiation. The visual evidence of the irradiation induced morphological change has been witnessed through electron microscopic studies. Typically, rods of 50nm length and 21nm diameter have transformed into particles of smaller dimension. Conversely, X-ray diffraction studies have revealed the lowering of crystallite size from 21.5nm to 9nm and an increase in microstrain by 11 times. Further, spectroscopic results, such as, significant blue shift (∼24cm−1) in vibrational features of Zn–O bonding, increase in native defect concentration in the nanostructures etc. also favor the irradiation led modification of nanostructures. It was anticipated that, dislodging and recrystallization of the constituent atoms of the elongated systems, as a consequence of suppression of the cohesive energy (owing to enormous energy deposition) caused by energetic ion irradiation, is chiefly responsible for the evolution of spherical nanoparticles.
