摘要: Pure ZnO and alkaline metal ion (Mg2+, Ca2+, Sr2+ Ba2+)-doped nanoparticles (NPs) were synthesized by the co-precipitation method. The retained wurtzite hexagonal structure, which was confirmed X-ray diffraction studies. micro-strain properties analyzed through Williamson–Hall analysis. oxidation states of elements (C (1s), O Zn (2p), Mg Ca Sr (3d) Ba (3d)) XPS HRSEM studies showed a reduction in thickness nanoflakes from 63 to 47 nm after doping. EDAX determined amount dopant (alkaline metals) incorporated into doped samples. FT-IR spectra Zn–O stretching bands at 432, 416, 414, 426 422 cm−1 for respective NPs. photoluminescence measurements revealed that broad emission composed six different due zinc oxygen vacancies. Thermal analysis irreversible structural transition occurred cubic phase antibacterial performed against set bacterial strains Mg-doped NPs possessed greater effect than other ion-doped
