STRUCTURAL, MORPHOLOGY AND PHOTOLUMINESCENCE PROPERTIES OF CERIUM DOPED ZINC OXIDE NANOPARTICLES PREPARED BY CO – PRECIPITATION METHOD

Abstract

Pure and Ce doped ZnO nanoparticles were synthesized by means of co-precipitation method. The structural analyses were done by X-ray diffraction (XRD) and it is several that the synthesized nanoparticles were well-crystalline and having hexagonal wurtzite structure of undoped ZnO and the nearness of Ce doped ZnO samples. The ascertained the normal crystallite measure from 27 to 42 nm with increment in Ce concentration. FESEM images delineated hexagonal shaped in ZnO nanoparticles. EDX affirms the synthesis of undoped and Ce doped ZnO nanoparticles. PL spectra affirmed that the intensityful Ce doping upgrades the visible emissions and smothers close band gap emission. The antibacterial effectiveness of Ce doped ZnO nanoparticles were explored against a Gram positive (Staphylococcus aureus) and Gram negative bacteria (E.Coli).
