Pure And Srba Dual Doped Zno Nanoparticles Prepared By Co-Precipitation Method And Their Structural, Optical And Antimicrobial Properties. International Journal of Pharmaceutical Sciences and Drug Research. 2019 Nov; 11(6): 284-2880975-248Xhttp://imsear.searo.who.int/handle/123456789/206262The present investigation, the successful preparation of pure ZnO (Z1) NPs and SrBa dual doped ZnO (Z2) NPs by chemical co-precipitation technique without use of any capping agent. The structural and morphological properties of Z1 and Z2 NPs were analyzed using X-ray diffraction (XRD) studies, Field emission scanning electron microscopy (FESEM), Elemental analysis (EDAX), Fourier transform infrared spectroscopy (FTIR). An optical property was studied by UV–Vis spectroscopy and Photoluminescence (PL) spectra. The antimicrobial activity of Z1 and Z2 NPs has been investigated against Staphylococcus aureus and Klebsiella pneumoniae bacterial strains. It has been interestingly observed that Z2 NPs has enhanced the inhibitory activity than that of Z1 NPs against S. aureus and more efficiently than the K. pneumoniae bacterial strain.Zinc OxideNanoparticlesXRDS. aureus and Antimicrobial activityJournal ArticleIndiaDepartment of Chemistry, Periyar Maniammai Institute of Science and Technology, Vallam, Thanjavur-613 403, Tamil Nadu, IndiaPost Graduate and Research Department of Chemistry, Jamal Mohamed College (Autonomous), Affiliated to Bharathidasan University, Tiruchirappalli-620 020, Tamil Nadu, IndiaDepartment of Chemistry, Jairams Arts and Science College, Affiliated to Bharathidasan University, Karur-639 003, Tamil Nadu, India
