In the proposed study, pure SrO2 and Zn@SrO2 were synthesized using a simple, effective, and economical sol–gel assisted hydrothermal technique (NPs). The structural, optical morphological, and biological activities of the prepared nanoparticles at various concentrations, such as 0, 10, and 20 wt%, were studied utilizing a variety of techniques. For pure SrO2 and Zn@SrO2 nanoparticles, the XRD showed tetragonal and hexagonal structures, respectively. When compared to Zn@SrO2 Nano particles, the pure SrO2 surface morphology variations, as seen by scanning electron microscopy (SEM). The examination of elemental compositions has determined that Sr, Zn, and O are present. Band gap (Eg) diminished from 5.92 to 5.65 eV with a rise in doping concentration, according to optical characterization of the sample, which was measured by UV–visible spectra. Diverse functional groups, including CO, OH, and CC, were validated using Fourier-transform infrared spectroscopy (FTIR). Gram-positive and gram-negative microorganisms were used in antibacterial investigations. The outcome showed that Zn@SrO2 particles had increased the antibacterial action against a bunch of microscopic organisms, and its presentation was enhanced with the gradual addition of Zn particle focus within SrO2 NPs.
