The incorporation of Sn into the Ca(OH)₂ matrix is investigated for the first time, providing insights into its impact on the structural, optical, and biological properties of the nanoparticles. A straightforward precipitation method was employed to synthesize pure and Sn-doped calcium hydroxide nanoparticles. The synthesized nanoparticles were characterized by using X-ray diffraction (XRD) pattern, ultraviolet–visible–near infrared (UV-Vis-NIR) spectra, Fourier Scanning Electron Microscope (FESEM) micrographs, and agar well diffusion method for antibacterial study. X-ray diffraction examinations confirmed the polycrystalline nature of the Ca(OH)₂ nanoparticles and revealed the structure to be hexagonal. The average crystallite size of the pure and Sn-doped Ca(OH)₂ nanoparticles are 49 nm and 66 nm, respectively. The FESEM images of the sample revealed the formation of pure Ca(OH)₂ nanoparticles in the form of nanoflakes and the change in the morphology while doping Sn with Ca(OH)₂. The prepared samples were assessed using UV-Vis-NIR spectra, showing the UV absorption band at approximately 247 and 263 nm for the samples of pure and Sn-doped Ca(OH)₂ nanoparticles, respectively. The calculated direct and indirect allowed band gap energies were found to be 4.04 and 3.92 eV for pure Ca(OH)₂, and 3.37 and 2.94 eV in the case of Sn-doped Ca(OH)₂. The antibacterial effectiveness of Ca(OH)₂ nanoparticles was assessed using the well diffusion method, and it was observed that both the samples of pure and Sn doped Ca(OH)₂ nanoparticles exhibited significant antibacterial properties against gram-negative bacterial strains. An elevation in Minimum Inhibitory Concentration (MIC) values for Sn-doped Ca(OH)₂ nanoparticles compared to pure Ca(OH)₂ nanoparticles was observed when examining their impact on Gram-negative bacteria (<em>Klebsiella pneumoniae</em>), which suggested a requirement for a higher concentration due to the nature of surface charges present in order to inhibit the growth of microorganisms.</div></div>","PeriodicalId":20056,"journal":{"name":"Phosphorus, Sulfur, and Silicon and the Related Elements","volume":"199 7","pages":"Pages 795-803"},"PeriodicalIF":1.4,"publicationDate":"2024-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143144737","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
