Finally, the centrifuge tube was sealed and left with a vent and stirred in a thermostatic water bath at 40 ℃ for about 24 hours. After the reaction is finished, deionized water is added for centrifugation for 5min at 3500rmp, and washing is repeated for 7 times until neutral Ti is obtained3C2And (3) solution. Putting the solution in a water bath ultrasonic machine with the power of 1000W for ultrasonic treatment for 1h, then centrifuging for 1h at 8000rmp to obtain a black solution, layering the solution by hand shaking, and taking out the upper dark green liquid, namely the few-layer Ti3C2A nanosheet solution.

And (3) performance testing:
(1) two-dimensional BP/Ti obtained in example 13C2The microstructure of the heterojunction is observed by a transmission electron microscope, wherein pictures of a common Transmission Electron Microscope (TEM) and a high-resolution transmission electron microscope (HRTEM) are shown in fig. 1 and fig. 2.
As shown in FIGS. 1 and 2, TEM and HRTEM tests prove that the BP nano material and Ti are combined3C2The nanosheets being stacked together by van der Waals forces to form a two-dimensional BP/Ti3C2Heterojunction, two-dimensional BP/Ti obtained3C2The heterojunction size is about 2um, and the lattice spacings 0.27nm and 0.14nm are respectively assigned to BP (040) and Ti3C2(110) Of (c) is performed.
(2) To, forTwo-dimensional BP/Ti obtained in example 13C2Performing ultraviolet-visible light absorption spectrum test on the heterojunction to obtain two-dimensional BP/Ti3C2The stability of the heterojunction in air and water environments was investigated, as shown in FIG. 3, two-dimensional BP/Ti3C2The heterojunction is exposed in air and water for 0-60h, and all absorption spectra have no obvious change, which indicates that the two-dimensional BP/Ti3C2The heterojunction has excellent environmental stability.
(3) Two-dimensional BP/Ti prepared in example 1 by Z-scan technique3C2The nonlinear optical properties of the heterojunction were studied, and absorption tests were performed at different intensities of 1550nm ultrafast pulsed laser, and the results are shown in FIG. 4, where two-dimensional BP/Ti was observed with the intensity of the mid-infrared incident light from 142nJ to 360nJ3C2The normalized transmission of the heterojunction gradually increased, indicating that two-dimensional BP/Ti3C2The heterojunction has strong nonlinear saturation absorption effect, and the characteristic is very important for Q-switching and mode-locked pulse lasers. The Z-scan curve is fitted by equations (1) and (2) as shown in fig. 5.
Two-dimensional BP/Ti3C2The absorption coefficient of the heterojunction is as in formula (1):
α＝α0+αNL(1)；
wherein, α0＝ln(TLN) L and αNLβ I is an absorbing and non-absorbing fraction, TLNIs the linear transmittance, L is the measured thickness of the sample, β is the nonlinear absorption coefficient, and I is the incident light intensity.
The Z-scan curve can be fitted by the following equation (2):
wherein β is the nonlinear absorption coefficient, I0Is the intensity at which z is 0,
is an effective measurement of the thickness of the sample, Z isLength of interaction of incident light intensity with sample medium, Z0Is the rayleigh length.
Further, the transmittance T has the following relationship with the incident light intensity I:
where I is the incident light intensity, Δ R is the modulation depth, IsatIs the saturation intensity, AnsIs an unsaturated loss.
Thus, the two-dimensional BP/Ti of example 1 can be calculated3C2β, Δ R, and I of the heterojunction in the mid-infrared bandsatRespectively are-0.269 cm/GW, 58.2% and 1.13GW/cm2Other two-dimensional materials such as BP have a Δ R of 12.4%, SnS has a Δ R of 12.5%, GeP has a Δ R of 21.94%. As can be seen, the two-dimensional BP/Ti prepared in example 1 of the present invention3C2Heterojunctions have a higher modulation depth at the same thickness than other two-dimensional materials. For a saturable absorber, a higher modulation depth value has a stronger modulation capability on the optical pulse.
In addition, the two-dimensional BP/Ti prepared in example 1 of the present invention3C2The lower saturation intensity of the heterojunction is more favorable for establishing a pulse laser, and the requirement on the light intensity in the cavity is relatively lower. The pronounced Saturable Absorption (SA) characteristics of these mid-infrared bands imply that the two-dimensional BP/Ti prepared according to example 1 of the present invention3C2Heterojunctions can potentially be applied to SA-based generated pulsed lasers.
In conclusion, the two-dimensional BP/Ti prepared by the method provided by the invention3C2The heterojunction has better stability in air and water, has good saturable absorption effect, and greatly expands two-dimensional BP/Ti3C2The use of (1).
