Sonochemical synthesis of zinc oxide nano particles

Zinc oxide nanoparticles were synthesized utilizing a green and simple sonochemical route. The synthesized ZnO nanoparticles were characterized for the analysis of structural and optical properties. Characterization with XRD and TEM shows that the synthesized particles were uniformly distributed, crystalline in nature with spherical shape and narrow size distribution of particles (48-50 nm). UV-Vis and PL spectra shows optical band gap to be 3.5 eV and ZnO sample possess fewer defect states. ZnO nanoparticles synthesized shows good optical properties and was observed to be a promising candidate to be used in thin film solar cells. Copyright © 2017 VBRI Press.
