“…For UV–vis spectrum analysis, light is cast into a specimen, causing the electron cloud around the nucleus of an atom in the specimen to resonate with the light, thus producing a specific absorption spectrum. The results indicated that PVA could stabilise [20], coat [21], and disperse silver nanoparticles [22]. Preventing from the aggregation and precipitation, silver nanoparticles prepared with PVA have a higher survival rate [23].…”

The study used arc discharge method (ADM) to produce silver nano-colloid in deionised water (DW), and compared the difference between pre-adding and post-adding of polyvinyl alcohol (PVA). First, they added 50 ppm of PVA into 200 mL silver nano-colloid, named Ag-PVA. Second, they added 50 ppm of PVA into 200 mL DW as the dielectrics and produced silver nano-colloid through it, named PVA-Ag. Then they compared the differences between two samples with several instruments. They examined wavelength and absorbance by using UV-visible spectrophotometer (UV-vis), used Zetasizer to measure particle size and zeta potential, adopted scanning electron microscope (SEM) and transmission electron microscope (TEM) to observe shape, size, and distribution of the silver nanoparticles in the colloid. The results indicated that colloid PVA-Ag had higher zeta potential and better suspension.

that satisfy the growing needs for compact, small foot-print, highly efficient and broadband photonic and optoelectronic devices. In other words, the development between SA technologies and lasers is almost isochronous. By 1983, several mode-locked fiber lasers with actively doped fiber amplifiers were demonstrated largely driven by improvements in low-loss optical fibers. However, mode-locking with a dye SA was unstable in Nd:fibers at the time. [5] The early 1990s saw the semiconductor SA mirror (SESAM) invention which was a milestone in the realization of stable passive mode-locked pulses [6,7] and stable Q-switching. However, SESAM progress was impeded by the narrow operation bandwidth, challenging fabrication process, slow relaxation time and most importantly a weak mid-infrared (mid-IR) response. By contrast, 2D nanomaterials can possess shorter relaxation times with a highly efficient broadband response covering even the mid-IR. The fabrication methods, nonlinear optical properties and applications in optics, biomedicine, and other fields of 2D materials are shown in Figure 1. 2D materials are now the spotlight of SA research applications because of these unique properties along with stable quantum confinement, higher mechanical stability, and an inherently small-footprint. [8][9][10] Graphene has been a breakthrough 2D NLO material for a wide range of topics such as broadband optical modulation, [11] optical frequency mixing, [12] ultrafast laser generation, [13][14][15][16][17][18][19][20] and surface plasmonic. [21] Nevertheless, the development of this material is still limited to some extent [22] due to its innate gapless band structure and the weak electronic on/off ratio. Topological insulators (TIs) reveal a large modulation depth. However, the fabrication of TIs is complicated because of their two elements composition. [23][24][25] Transition metal dichalcogenides (TMDs) are unusable in the mid-IR region because of their large bandgaps. [26] In Group-VA monoelemental materials, black phosphorus (BP) is famous for the characteristic layer number dependent bandgap. [27][28][29][30][31][32][33][34][35] However, monolayer or fewlayer BP lacks of chemical stability at ambient conditions. [36,37] In addition, another Group-VA material, semiconducting antimonene, is relatively stable under ambient environment with a wide bandgap. [38] Bulk antimonene has great potential to become a TI as well as quantum spin Hall phase producer when the number of layers is under 22, respectively. [39] On top of this, antimonene is very chemically stable. It has good thermal conductivity, [40] high mobility, [41] excellent thermoelectric figure of merit, [42] and good optical properties, [43][44][45][46] which 2D materials have received significant attention from the scientific community due to their unique structures and excellent physical properties. A lot of applications are explored based on graphene, topological insulators, and transition metal dichalcogenides. With further development of 2D materials, other Group-VA...

“…Guo et al (2016) investigated the stability of tungsten diselenide (WSe 2 ) as a saturable absorber material in an all-PM Q-switched erbium-doped fiber laser. They observed stable Q-switched operation for 1.6 h under a pump power of 280 mW [ 23 ]. Chen et al (2023) reported a single-frequency linearly polarized Q-switching operation at 1.06 μm based on Nb 2 GeTe 4 SA.…”
