“…PL measurements show the near-band-edge (NBE) emission at around 375 nm and the defect-luminescence In order to study the binding energies of the nanocomposite, the O 1s, Zn 2p, S 2p, and Au 4f XPS spectra were measured, as shown in Figure 4a-d. In comparison to the ZnO/ZnS core shell structures [26], Au NPs have lower binding energies for O 1s, Zn 2p, and S 2p since incorporating Au NPs may weaken the binding energies [26,27]. In addition, Au 4f exhibited a three-peak profile for the Au NPs, as shown in Figure 4d.…”

ZnO/ZnS nanocomposite-based nanostructures exhibit dual light and gas sensing capabilities. To further boost the light/dual sensing properties, gold nanoparticles (Au NPs) were incorporated into the core-shell structures. Multiple material characterizations revealed that Au NPs were successfully well spread and decorated on ZnO/ZnS nanostructures. Furthermore, our findings show that the addition of Au NPs could enhance both 365 nm UV light sensing and hydrogen gas sensing in terms of light/gas sensitivity and light/gas response time. We postulate that the optimization of gas/light dual sensing capability may result from the induced electric field and inhabitation of electron-hole recombination. Owing to their compact size, simple fabrication, and stable response, ZnO/ZnS/Au NPs-based light/gas dual sensors are promising for future extreme environmental monitoring.
