“…Raman spectra test is a powerful tool to analyze the microscopic structure of samples (Figure b). For pure ZIS, the peaks about at 243 and 343 cm –1 are in line with a previous report. , Two main characteristic peaks of the NU66 are in accord with the previous literature . For the NU66/ZIS composites, when the amount of NU66 is up to 5%, the main characteristic peaks of NU66 located near 1600 cm –1 are detected in the composites.…”

The introduction of metal−organic framework materials into photocatalysts is considered to be an effective strategy for improving the transfer and separation efficiency of photogenerated electron−hole pairs. In the present study, we demonstrate the delicate construction of NH 2 -UiO-66/ZnIn 2 S 4 (NU66/ZIS) composites as bifunctional photocatalysts with the degradation efficiency of malachite green (98%) and the hydrogen evolution rate of a 10% NU66/ZIS composite reaching up to 2199 μmol h −1 g −1 . The characterization of unique ZIS/NU66 shows that it can efficiently facilitate the separation and transfer of light-induced charges and exposed rich active sites for photocatalyst redox reaction. Moreover, the results of vitro cytotoxicity assay suggest that NU66/ZIS composites are potential safety photocatalysts to the environment and human beings. Furthermore, the DFT calculation indicates that the Zr site of NU66 and In site of ZnIn 2 S 4 interface should be the main active center in NU66/ZIS heterojunctions.

“…[29,30] The spectra shows the characteristic peaks of the ZnIn 2 S 4 hexagonal structure assigned respectively to the F 2g , F 1u (TO 1 ), F 1u (LO 1 ), F 1u (TO 2 ), F 1u (LO 2 ), and A 1g vibrational modes and the spectra is in agreement with previous reports. [31] X-ray photoelectron spectroscopy (XPS) was used to confirm binding states and stability of ZnIn 2 S 4 . For comparison reasons, the XPS spectra were collected from freshly cleaved flake as well as from flake that was exposed to ambient atmosphere for 2 months.…”

Zinc indium sulfide belongs to the family of layered ternary chalcogenides. Although ZnIn2S4 has a suitable bandgap in the visible range, its optoelectronic properties are not fully investigated. Most photodetectors based on layered semiconductors suffer from large dark currents, which hamper their performance and energy efficiency. In this work, high quality ZnIn2S4 single crystals are synthesized via chemical vapor transport. The free‐standing crystals are ≈20 μm thick and up to 2 cm2 in area and produce large photocurrents upon UV–vis illumination, while also maintaining extremely low currents in the dark. This allows to fabricate a simple photodetector with ohmic contacts, exhibiting extremely small dark currents down to 10–12 A. The ON/OFF (light/dark) switching ratio reaches value of 106, the highest reported for a layered semiconductor. Furthermore, the photodetector exhibits remarkable responsivity of 173 A W–1 and excellent detectivity of 1.7 × 1012 Jones. To demonstrate sensitivity and flexibility of the ZnIn2S4 crystals, a wearable device is also fabricated. The wearable is able to record human heart rate and compare it with signal measured by a commercial smartwatch. The results suggest a substantial research potential in further explorations of ZnIn2S4 and other ternary chalcogenides for optoelectronic applications.
