Franckeite, a natural van der Waals heterostructure with excellent physicochemical characteristics, has shown great potential for high-performance optoelectronic device. Here, the few-layer franckeite nanosheets have been prepared by liquid phase-exfoliation method successfully, and nonlinear optical absorption carrier dynamics behaviors of studied experimentally. The show wavelength- intensity-dependent exhibit ultrafast dynamic process. nonlinearity in further validated via an Er3+-doped fiber laser to deliver stable femtosecond pulse. experimental results reveal that can be ideal candidate design manufacture devices.
