摘要: Abstract Facile, rapid, and environmentally benign hybrid Ag-ZnO nanocomposites were synthesized by two steps from green synthesis approach at room temperature. The absence of an impurity peak in X-ray diffraction (XRD) pattern confirmed the formation polycrystalline nanocomposite material. An additional (111) Ag was detected along with ZnO crystalline wurtzite structure. surface area electron (SAED) further crystallinity nanocomposites. compositional analysis determined EDS-mapping presence Zn, O composite. room-temperature photoluminescence (PL) spectra depict a weak ultraviolet (UV) emission 385 nm, strong visible ∼600 nm, while increasing concentration to matrix, UV completely disappeared major moved ∼500 nm indicated best optimal detection for sensors. fluorescence measured respect concentrations temperature investigate functionality selectivity nanomaterials. This work opens notable way fabricate nanohybrids, makes significant contribution based sensor applications.
