Two-dimensional MXene Ti₃C₂ for Efficient Photoacoustic Conversion

Abstract

Two-dimensional MXene are potential photoacoustic conversion materials due to the excellent light absorption and photothermal conversion efficiencies. In this study, we theoretically analyze and experimentally demonstrate the photoacoustic properties of Ti3C2. High-intensity ultrasonic waves are generated by irradiating Ti3C2 films with 532 nm pulsed laser. By comparison, the signal amplitude of Ti3C2 is about twice as much as that of graphene. We validate the potential of Ti3C2 as an efficient functional material for photoacoustic or laser ultrasonic applications.
