XRD confirmed phase-pure hexagonal CeF? with an average crystallite size of ~ 24nm. TEM showed uniformly distributed nanoparticles (812nm), and lattice fringe analysis revealed an interplanar spacing of ~ 0.315nm corresponding to the (111) plane, indicating preserved crystallinity after SA functionalization. UVvisible spectroscopy revealed a reduction in the optical band gap from 6.05eV (CeF?) to 4.96eV (CeF?SA), indicating modification of electronic properties. PL emission (351522nm) showed quenching, suggesting suppressed charge carrier recombination and increased defect density. CeF?SA exhibited antimicrobial activity against Gram-positive (S. aureus, S. pneumoniae), Gram-negative (K. pneumoniae, E. coli), and the fungal pathogen C. albicans, with reduced MIC (650g/mL) and MBC (1050g/mL) against K. pneumoniae. SEM revealed pronounced bacterial membrane damage. In vitro MTT assays on L929 fibroblasts demonstrated &gt; 80% cell viability at concentrations up to 60g/mL, indicating the nanoparticles are well-tolerated at sub-antimicrobial doses. Overall, CeF?SA represents a promising antimicrobial nanoplatform, with further studies needed to assess cytocompatibility at MIC-level concentrations.
