AB  - Pure and zinc-doped CdO NPs (Zn-CdO NPs) were synthesized through a facile 
      co-precipitation method. The structural, morphology, chemical composition, 
      optical and antibacterial activity of the NPs were studied with respect to pure 
      and Zn-doped CdO concentration (0-7.5mol.%). Scanning electron microscope (SEM) 
      images reveal that pure and Zn-doped CdO NPs were in the nano-scale regime with 
      different crystalline morphology. The energy dispersive X-ray spectroscopy (EDS) 
      spectrum predicts the presence of Cadmium (Cd), Zinc (Zn) and Oxygen (O) in the 
      prepared samples. Optical studies divulge that Zn(2+) doping CdO decreases the 
      band gap energy (Eg) (3.36-3.02eV) with an increase in Zn(2+) doping 
      concentration. Optical absorption spectrum of CdO red-shifted as the Zn 
      concentration varied from 2.5mol.% to 7.5mol.%. PL spectra displayed a strong UV 
      emission peak at 380nm. Enhanced Visible emission at 430 and 522nm with Zn(2+) 
      doping interprets the defect density in CdO by occupying Cd(2+) vacancies with 
      Zn(2+) ions. Photocatalytic studies revealed that 7.5% Zn-doped CdO NPs show 
      maximum degradation for atrazine (ATZ) as herbicide pollution under UV 
      irradiation. Antibacterial studies against (Gram positive) and (Gram negative) 
      bacteria's authenticate that Zn(2+) doped CdO nanostructures exhibit excellent 
      antibacterial activity against all bacteria's with an increase in doping 
      concentration.
