Dynamics for the interfacial electron migration in the Co-P/BP nanosheets. a TAS spectra of the BP nanosheets. b TAS spectra of the Co-P/BP nanosheets. c Time profiles of the normalized transient absorption at 1020 nm. The data in Fig. 6c were fitting by biexponential function. All the spectra are obtained by the excitation of a 500 nm pulsed laser
