Abstract: Fluorine doped CdO nanoparticles (F-CdOnps) were obtained by chemical reaction method. Optical, structural, vibrational and morphological properties of F-CdOnps were examined by UV-vis optical absorption spectroscopic, X-ray diffraction, Fourier transform infrared spectroscopic and Transmission electron microscopic techniques. These prepared F-CdOnps show face centred cubic (FCC) crystalline structure, lesser size, and higher band gap, strain and dislocation density with respect to pure CdOnps. Formation of nanoparticles was confirmed from TEM and SEM images. The consequences of the antibacterial studies confirm the superior aptitude of F-CdOnps with respect to pure CdOnps to inhibit the growth of both bacteria namely Pseudomonas aeruginosa (gram negative) and Bacillus cereus (gram positive).
