“…Additionally, two peaks at 231.8 and 228.8 eV correspond to the Mo 3d 3/2 and 3d 5/2 states in metallic 1T-phase MoS 2 , respectively. Notably, the binding energies of 1T-phase were about 0.8 eV lower than those of 2H-phase overall . The S 2p spectrum (Figure e) also displays four characteristic peaks.…”

“…Certainly, one can achieve the coexistence of phases by fine-tuning parameters, such as temperature, 88,120 pressure, 121,122 reducing atmosphere, 88 composition, 66,123 and catalysts. 69,90,124−126 Recently, there has been a surge in the emergence of various methods for achieving the coexistence of phases through CVD, including flux-controlled CVD for mixed-dimensional heterostructures, 127 single-step CVD for 1T/2H-MoS 2 heterostructures, 120 Sb 2 O 3 and NaCl-assisted CVD-yielded coexistingphase 1T/2H-MoS 2 , 69 and rhenium doping facilitated the controlled synthesis of 1T/2H-MoS 2 films. 125,126 The flexibility in tuning the parameters of CVD allows for the controlled preparation of coexisting phases in both lateral and vertical structures.…”

“…In the CVD process for the synthesis of coexisting TMDC phases, the key factors are temperature and gas flow for the control of the nucleation and growth rates of different phases. Certainly, one can achieve the coexistence of phases by fine-tuning parameters, such as temperature, , pressure, , reducing atmosphere, composition, , and catalysts. ,, Recently, there has been a surge in the emergence of various methods for achieving the coexistence of phases through CVD, including flux-controlled CVD for mixed-dimensional heterostructures, single-step CVD for 1T/2H-MoS 2 heterostructures, Sb 2 O 3 and NaCl-assisted CVD-yielded coexisting-phase 1T/2H-MoS 2 , and rhenium doping facilitated the controlled synthesis of 1T/2H-MoS 2 films. , …”

“…8−11 Among various fabrication processes, chemical vapor deposition (CVD) has emerged as the most accessible, cost-effective, and straightforward method for producing high-quality MoS 2 , 12−17 with diverse morphologies, including planar and vertical triangles, 18−21 nanowires, 22 and nanosheets. 23,24 This variety morphology enhances MoS 2 's light absorption and specific area, facilitating a larger contact interface between MoS 2 and the analyte. These unique characteristics have prompted studies exploring MoS 2 's optical sensing capabilities for detecting various contaminate dyes, such as rhodamine, 25 methylene blue (MB), 26 and methylene orange.…”

“…Consequently, shielding the MoS 2 surface from the analyte prevents its poisoning, potential degradation, or long-term aging induced by contact with the MB-containing solution. As the MB concentration in water increases, there is a corresponding augmentation in the overall MB optical absorption peak at around 664 nm, 24 thereby directly impacting the device's reflectivity and causing exciton dynamics. Consequently, monitoring the exciton dynamics facilitates the direct detection of various MB concentrations.…”
