Investigation on the structural, optical, photoluminescence, and antimicrobial properties of charged surfactants (CTAB, SDS), and uncharged surfactant (PEG) assisted ZnO/MgO nanocomposites

Different surfactants (CTAB, SDS, and PEG) assisted ZnO/MgO nanocomposites were synthesized by wet chemical route. The hexagonal/cubic system of ZnO/MgO was obtained in the XRD patterns for all synthesized composites. Particle morphologies were tuned in each surfactant in the SEM studies. The synthesized composites related entities were traced by EDX analysis. Narrow band gaps were found in the optical absorption spectra of the composites. Prominent visible emission peaks were detected at 680 nm in all synthesized ZnO/MgO from the PL measurement.The antimicrobial activity of CTAB-assisted ZnO/MgO was analysed against E.coli and S. aureus, and its results were discussed in detail.
