Liquid Phase Exfoliation

We fabricated few-layered MoSe2 nanosheets via the simple ultrasonic-assisted liquid phase exfoliation (UALPE) method. Typical characterizations and testing were exploited to confirm the nonlinear absorption properties of MoSe2 nanoflakes. A passively Q-switched Nd:YVO4 laser emitting 1 [Formula: see text]m wavelength was demonstrated with the as-prepared MoSe2 saturable absorber (SA). The stable pulses were generated with a maximum output power of 215 mW and a shortest pulse width of 192 ns. The experimental data provided a solid base for the photonics applications of MoSe2 nanomaterials.

Liquid Phase Exfoliation

In this study, β-antimonene nanosheets were exfoliated using liquid-phase exfoliation assisted by sonication. The nonlinear absorption properties of β-antimonene nanosheets were systemically investigated. Our results demonstrate that antimonene is a promising candidate as a saturable absorber and an optical limiting material.

Pretreatment Conditions

Liquid phase exfoliation (LPE) is widely used to produce colloidal dispersions of nanomaterials, in particular two-dimensional nanosheets. The degree of exfoliation, i.e., the length to thickness aspect ratio was shown to be intrinsically limited by the ratio of in-plane to out-of-plane binding strength. In this work, we investigate whether simple pretreatment of the starting material can be used to change the in-plane to out-of-plane binding strength through mild intercalation to improve the sample quality in sonication-assisted LPE. Five different pretreatment conditions of WS2 were tested and the dispersions size-selected through centrifugation. From optical spectroscopy (extinction, Raman, photoluminescence), information on nanosheet dimension (average lateral size, layer number, monolayer size) and optical quality (relative photoluminescence quantum yield) was extracted. We find that the pretreatment has a minor impact on the length/thickness aspect ratio, but that photoluminescence quantum yield can be increased in particular using mild sonication conditions. We attribute this to the successful exfoliation of nanosheets with a lower degree of basal plane defectiveness. This work emphasizes the complexity of the exfoliation process and suggests that the role of defects has to be considered for a comprehensive picture.
