Morphologies, crystal structure and antibacterial properties of chromium substituted zinc oxide nanoparticles synthesized by microwave method

Abstract In this paper, we report on the synthesis on pure and Cr doped ZnO particles via the microwave method. Pure and Cr doped ZnO produced are monodisperse and versatile and were characterized with the help of FT-IR, XRD, SEM/EDX and TEM methods. Pure and Cr doped ZnO particles are crystalline in nature and average sizes were between 20 and 30 nm. Furthermore, the present work clearly indicated that the surface area to volume ratio and particle size variation of green ZnO nanoparticles are accountable for significantly increased antibacterial behaviour.
