摘要：In the proposed work, a facile convenient and meagre method of sol-gel assisted hydrothermal method was used for the synthesis of pure zinc oxide nanoparticles (ZnO NPs). The structural and optical morphology are inspected using various techniques of the synthesized nanoparticles and at different molar concentrations of 1, 2 and 3 moles respectively. The X-Ray Diffraction (XRD) pattern revealed the hexagonal crystal structure for pure ZnO nanoparticles and the crystal size is noted to be increasing with the increase in concentration. The Scanning Electron Microscope (SEM) illustrated the crystalline growth being proportional to the concentration of nanoparticles. The Fourier Transform Infrared Spectroscopy (FTIR) confirmed the presence of various functional groups such as O-H, C-O, -C-O-C, C-H and C-N groups. The elemental composition studied using Energy- Dispersive X-Ray Spectroscopy (EDX) revealed the presence of Zn and O particles and the purity of ZnO NPs were noted. Optical characterization of the sample using UV-Vis-NIR Spectroscopy revealed the band gap (Eg) being decreased from 5.91eV to 5.11eV with the increase in molar concentration of ZnO NPs. Anti- bacterial studies were carried out at pre- defined concentration (25 m/l to 100 m/l) using gram positive and gram-negative bacteria to test the potential of synthesized ZnO NPs as inhibitory agents.
