“…In addition, MOFs, COFs and graphyne also exhibit excellent nonlinear optical properties [500][501][502][503][504] . 2D layered NMDs have been attracting extensive attention because of their unique nonlinear optical properties [505][506][507][508] . Tsang et al 509 studied the nonlinear absorption properties of PtS2 and demonstrated that it can be used in optical limiters and biosensors.…”

Research on two-dimensional (2D) materials has been explosively increasing in last seventeen years in varying subjects including condensed matter physics, electronic engineering, materials science, and chemistry since the mechanical exfoliation of graphene in 2004. Starting from graphene, 2D materials now have become a big family with numerous members and diverse categories. The unique structural features and physicochemical properties of 2D materials make them one class of the most appealing candidates for a wide range of potential applications.In particular, we have seen some major breakthroughs made in the field of 2D materials in last five years not only in developing novel synthetic methods and exploring new structures/properties but also in identifying innovative applications and pushing forward commercialisation. In this review, we provide a critical summary on the recent progress made in the field of 2D materials with a particular focus on last five years. After a brief background 物理化学学报 Acta Phys. -Chim. Sin. 2021, 37 (12), 2108017 (3 of 151) introduction, we first discuss the major synthetic methods for 2D materials, including the mechanical exfoliation, liquid exfoliation, vapor phase deposition, and wet-chemical synthesis as well as phase engineering of 2D materials belonging to the field of phase engineering of nanomaterials (PEN). We then introduce the superconducting/optical/magnetic properties and chirality of 2D materials along with newly emerging magic angle 2D superlattices. Following that, the promising applications of 2D materials in electronics, optoelectronics, catalysis, energy storage, solar cells, biomedicine, sensors, environments, etc. are described sequentially. Thereafter, we present the theoretic calculations and simulations of 2D materials. Finally, after concluding the current progress, we provide some personal discussions on the existing challenges and future outlooks in this rapidly developing field.

In this work we show the possibility of imparting polarization-sensitive properties to two-dimensional films of graphene-like semiconductors, using WSe2 as an example, by the application of ordered silver triangular nanoprisms. In addition, such nanoprisms made it possible to increase the optical sensitivity of optical detectors created on two-dimensional films by a factor of five due to surface plasmon resonance. The peculiarities of the surface plasmon resonance were shown by theoretical modeling, and the optimal conditions of its occurrence were determined. This article demonstrates an effective approach to creating spectrally selective, polarization-sensitive detectors based on two-dimensional graphene-like semiconductors.

“…According to previous reports, the PL enhancement of MoS 2 was closely related to the stacking sequences of MoS 2 and plasmonic nanoscale metals. 25 The sandwich-like three-layer hybrids possess higher PL-enhancing ability. However, to our knowledge, a three-layer plasmonic hybrid that is composed of TMDs and metallic NPs fabricated through physical deposition methods has not been reported.…”

In this work, a feasible method was proposed to prepare MoS 2 -based plasmonic hybrid systems with high photoluminescence (PL) emission enhancement. The enhancement effect of plasmonic hybrids on the PL emission of MoS 2 has been systematically studied on MoS 2 /Ag spherical nanoparticle (SP) hybrid systems with different architectures by changing the stacking position of Ag SPs. It is demonstrated that the sandwich-like hybrid composed of monolayer MoS 2 and dielectric Al 2 O 3 layer between two layers of Ag SPs has the highest PL enhancement. Remarkably, after adding an Al 2 O 3 layer under MoS 2 , the PL intensity enhancement up to 209 times was achieved in the sandwich-like hybrid system. Compared with the hybrid with single-layer SPs, the sandwich-like hybrid system with double-layer Ag SPs exhibited an obvious blue shift as a result of the selective enhancement of the A 0 exciton in MoS 2 . These results demonstrate that MoS 2 /Ag SP hybrid nanosystems have significant implications for sensing and photoelectronic devices.
