“…In recent years, emerging 2D materials including black phosphorus, [1,2] MXenes, [3,4] graphdiyne, [5,6] transitionmetal dichalcogenides, [7,8] and metal halides MX n (M = metal, X = Cl, Br, I, n = 2, 3) [9][10][11][12][13][14] have attracted tremendous interest due to their excellent electrical, optical, and magnetic properties. Among these materials, 2D layered binary iodides with bandgaps in the range of 1.1-1.7 eV, that is, BiI 3 , [9][10][11] PbI 2 , [12] and RhI 3 , [13,14] have been found to have excellent properties for optoelectronic applications.…”

Constantly exploring and improving the photoelectric properties of functional materials is of paramount importance for the development of the optoelectronics industry. Herein, a new strategy to extend the spectral response range and enhance the photoelectric properties of functional materials using high pressure is presented. In addition, the successful application of this strategy to the regulation of the photoelectric properties of 2D layered semiconductor iodine is reported. The maximum photocurrent is four orders of magnitude higher than that measured under initial pressure, with visible‐light illumination. Impressively, the light‐response range of iodine is successfully extended to the near‐infrared (1064 nm) with the application of pressure, and the photoresponse properties are also significantly enhanced with compression. These dramatically enhanced photoelectric activities are attributed to charge delocalization as well as an increased charge density in the regions between parallel molecules, which occur as a result of pressure‐induced charge transfer in the iodine molecules. These findings can be extended to guide the modification of the spectral response range and photoelectric properties of other functional materials.

“…Three atomic structures have been discovered for the MXene family, respectively, M 2 X, M 3 X 2 , and M 4 X 3 , providing great possibility and tenability for exploring and exploiting diversiform materials according to particular demands. [80,81] Additionally, the MXene family have been expanded again with two new synthetic MXene subfamilies in recent years, the ordered double-transition metal MXene, respectively M′ 2 M″C 2 and M′ 2 M″ 2 C 3 , where M′ and M″ are two different early transition metals. [82] Up to now, nearly thirty kinds of MXene have been fabricated successfully, including synthetic Ti 3 C 2 , Ti 2 C, Ti 3 CN, Ta4C3, Nb 2 C, V 2 C, (Ti 0.5 Nb 0.5 ) 2 C, and (V 0.5 Cr 0.5 ) 3 C 2 .…”

Moreover, a study from the World Health Organization (WHO) emphasized that death due to heart diseases and diabetes is still an upward trend and expected to be the first and seventh leading causes of death, respectively, by 2030. [16] Therefore, early diagnosis and treatment is urgently on demand. [12,17] A variety of human health-detection devices, intelligent wearable devices, and medical intelligent devices as efficient strategies have been emerging and making a big difference in daily life, [18][19][20][21][22][23] making it higher efficient, more accurate, more timely than traditional detection techniquesIn the meanwhile, sensors, as a vital component in intelligent detection devices quickly bloom to meet the requirement of high sensitivity, wide detection range, and stable response sensing capability. Sensors work through transforming external stimulus including biological, chemical, and physical changes into electrical signals changes. According to their respective work mechanism, sensors can be classified into the following several categories: piezoresistive, [24][25][26] piezoelectric, [27][28][29] frictional, [30] and capacitive. [31][32][33][34] Among them, piezoresistive sensors have attracted extensive concern for its simple structure, low cost, and easy signal acquisition, further being applied to the field of wearable detection devices. [35,36] It works by transforming external stimulus into visual electrical signals, and the change of resistance is generated by microscopic deformations of its own structure. [37][38][39][40] From sensors functional point of view, sensors can also be divided into strain sensors, [39,[41][42][43][44] stress sensors, [45,46] humidity sensors, [47] gas sensors, [41,48,49] temperature sensors, [50] and so on. On the present overall view, the key issue focuses on how to realize ideal sensors compatible with high sensitivity, wide detection range, ultralow response time, ultralow detection limitation, superb linearity, and cyclic stability. [51][52][53][54][55][56][57][58][59][60] What is noteworthy is that conductive materials interacting with other substances have been considered as an extremely efficient strategy to realize high sensing performance, being able to give out fast response reacting to outer tiny changes. Currently, aiming to endow sensors superb sensitivity and wide sensing range, flexible substrates for sensors commonly choose polydimethylsiloxane (PDMS), hydrogenated styrene-butadiene block copolymer (SEBS), and silicone rubber and other high elastic polymer materials. [37,57,61,62] Then, the composite sensor is fabricated successfully by different preparation techniques including With the advent of the era of intelligent manufacturing, sensors, with various detection objects, have set off a wave of enthusiasm and reached new heights in medical treatment, intelligent industry, daily life, and so on. MXene, as an emerging family of 2D transition metal carbides/nitrides, possesses impressive electrical conductivity, outstanding structural controllability, ...

absorbers (SAs) are widely used to obtain ultrafast lasers. Mode-locking indicates a fixed phase between longitudinal modes in spectral domain, while Q-switching refers to the giant pulse formation due to the tunable Q factor of the laser cavity. Saturable absorption represents the optical modulation that absorption coefficient of SAs decreases with the increase of incident optical intensity, where SAs are often categorized into artificial and real SAs. [7][8][9] Artificial SAs mainly consist of nonlinear polarization evolution, [10,11] nonlinear optical loop mirrors, [12][13][14] and nonlinear amplification loop mirrors, [15,16] which fulfill the function of saturable absorption by means of nonlinear effects. By contrast, real SAs are characterized by the inherent nonlinear absorption property of the materials. Semiconductor saturable absorber mirror is a typical real SA and widely used in diverse lasers. However, several drawbacks such as complex fabrication and narrow operating bandwidth restrict its applications. [17][18][19][20][21] Under such circumstances, nanomaterials emerge as SAs of distinction where 2D nanomaterials have been widely investigated because of the unique optical properties induced by the energy band structures. [22][23][24][25][26][27][28] Graphene possesses zero bandgap and ultrafast carrier dynamics properties, contributing to a broad operating bandwidth and fast response time. [29][30][31][32][33][34][35][36] Nevertheless, the modulation depth of ≈2.3% per layer limits Nanomaterials with outstanding optical properties are widely used in ultrafast photonics. Especially, metal nanomaterials have attracted increasing attention in recent years owing to the surface plasmon resonance that further enhances their nonlinear optical response, making them suitable for generating ultrafast pulses in a wide range of wavebands. Herein, the fabrication and integration processes of typical metal nanomaterials such as gold, silver, and copper, as well as their applications in ultrafast lasers are reviewed. The synthesis methods of metal nanomaterials, which can be divided into dry and wet methods, are first introduced with their characteristics and advantages summarized. Moreover, the integration approaches that are used to incorporate metal nanomaterials into laser cavities are discussed, where sandwich structure based on polymer film and deposition method, as well as evanescent-wave structure based on D-shaped and tapered fiber are demonstrated. Besides, the state of the art of typical ultrafast lasers enabled by metal nanoparticles is systematically reviewed. Finally, current challenges and perspectives on the development of ultrafast photonics enabled by metal nanomaterials are proposed.
