“…In CBD, solution pH/bath pH (a measure of the acidity or basicity of a solution) is an important parameter because it directly affects the growth mechanism as well as reaction rate. Therefore, it can influence the formation of phases and physical properties of films [ 27 ]. In addition, the bath pH must be at a specific optimum value to maintain supersaturation condition (Q ip > K sp , Figure 5 c) for the formation of Sn x S y films.…”

“…The bath pH can also influence the growth mechanism, which leads to phase transformation [ 184 , 185 ]. An o-SnS forms at a lower pH of 6.5 via the cluster-by-cluster mechanism, whereas c-SnS forms at a higher pH of 7.0 through the ion-by-ion mechanism ( Figure 7 n,o) [ 27 ].…”

“…The phase transition caused by the change in bath pH leads to a change in the morphologies of the film surfaces ( Figure 7 o) and the energy band gaps (o-SnS: 1.51 eV and c-SnS: 1.64 eV) ( Figure 7 p) [ 27 , 184 , 185 ]. The increase in solution pH results in the decrease of free Sn 2+ ion concentration as well as the concentration of OH − ions, which are favorable for the hydrolysis of the S ion source [ 256 ], leading to the increase in the concentration of S 2− ions.…”

The rapid research progress in tin-based binary sulfides (SnxSy = o-SnS, c-SnS, SnS2, and Sn2S3) by the solution process has opened a new path not only for photovoltaics to generate clean energy at ultra-low costs but also for photocatalytic and thermoelectric applications. Fascinated by their prosperous developments, a fundamental understanding of the SnxSy thin film growth with respect to the deposition parameters is necessary to enhance the film quality and device performance. Therefore, the present review article initially delivers all-inclusive information such as structural characteristics, optical characteristics, and electrical characteristics of SnxSy. Next, an overview of the chemical bath deposition of SnxSy thin films and the influence of each deposition parameter on the growth and physical properties of SnxSy are interestingly outlined.

“…For example, the absorption coefficient of SnS nanosheets can be up to ≈10 4 cm −1 and the photoelectric conversion efficiency can be up to 24%, which indicates that SnS nanosheets are very suitable for use as light absorption layer in solar cells. In addition, it has been widely used in water decomposition photocatalysts, photodetectors, gas sensors, biosensors, field effect transistors, thermoelectric devices, electrochemical capacitors, supercapacitors, high‐performance anode materials in lithium‐ion batteries, and sensitive photodetectors . More fascinating is that SnS is nontoxic, rich in earth resources, environmentally friendly, low‐cost, and has other excellent characteristics, so it is of great significance to further explore SnS nanosheets .…”

As a member of the 2D group IV monochalcogenides (MX; M = Sn, Ge; X = S, Se), SnS has attracted great interest due to its outstanding optical, electrical, and optoelectronic properties. Especially, SnS nanosheets material have a large absorption coefficient and high photoelectric conversion efficiency, it can be potentially used in optical modulators, saturable absorbers, solar cells, supercapacitors, and other optical devices. However, the nonlinear optical properties of SnS nanosheets and their applications in ultrafast photonics are seldom studied. In this paper, the nonlinear optical properties of SnS nanosheets have been characterized through a dual‐balance detection system, whose modulation depth is 5.8%. More importantly, 105th harmonic soliton molecule based on SnS saturable absorbers has been realized for the first time to the authors’ knowledge. A compact mode‐locked fiber laser with a pulse duration of 1.02 ps and a repetition rate of 459 MHz is realized near 1.5 µm. It is demonstrated that SnS nanosheets have outstanding nonlinear properties and play an extremely important role in the field of ultrafast photonics.
