Dynamics of broadband photoinduced species and enabled photodetection in MXenes

Abstract Dynamics of photoinduced species, as a key parameter for nanomaterials plays significantly role in the performance optoelectronic devices. In this work, origin broadband optical response emerging Ti 3 C 2 T x MXene is revealed by transient spectroscopic analysis. From ultraviolet to infrared, steady-state and responses present wavelength-related features. The carrier lifetime found change from femtosecond nanosecond time scale dominated various i.e., surface plasmon. unique character enables photodetection. This fundamental study on carrier, plasmon dynamics, application photodetection helpful exploring MXene-based
