Amorphous/Crystal Heterostructure Coupled Oxygen Vacancies‐Sensitized TiO2 with Conspicuous Charge‐Transfer Resonance for Efficient SERS Detection of Chloramphenicol (Advanced Optical Materials 23/2023)

Amorphous/Crystal Heterostructure Coupled Oxygen Vacancies‐Sensitized TiO2 with Conspicuous Charge‐Transfer Resonance for Efficient SERS Detection of Chloramphenicol In article number 2301609, Xiang‐Hu Tang, Xing‐Jin Huang, Wen‐Qing Liu, and colleagues constructed a crystal‐amorphous CA‐V‐TiO2 SERS substrate with rich oxygen vacancies. The energy level matching and charge transfer resonance phenomenon were realized, and the SERS property of the substrate was optimized, which could realize the ultrasensitive detection of trace chloramphenicol in the actual water environment.
