WebAug 29, 2024 · In the FTIR spectra of the ZnS materials at different sulfurization temperatures as shown in Figure 3(a), the absorption peaks occur at about 3462 cm-1 and 1637 cm-1, which can be ascribed to the stretching and bending vibration of the O-H and H-O-H bands from external surface water molecules, respectively. WebFTIR and UV–Vis spectroscopy establishes the presence of all major Zn and S bonding in the sample with slightly increased optical band gap as compared to the bulk ZnS. The larger band gap is related to smaller particle size supported by the XRD data. To understand the light emission behavior of the ZnS NPs, PL spectroscopic analysis was done.
