Synthesis, local structure and optical property studies of α-SnS microrods by synchrotron X-ray pair distribution function and micro-Raman shift

Abstract: The PDF refinement shows layer structure of SnS-A with two distinct bond lengths, one nearly parallel to the ‘a’ axis and another perpendicular to the ‘a’ axis, it corresponds to bond lengths of 2.62528 (38) Å and 2.66204 (03) Å.

“…The broad peak at 617 cm −1 may be caused by the deformation mode of sulfate in SnS, while the Raman peaks at 93 and 232 cm −1 are attributed to transverse and longitudinal optical A g vibrational modes and 309 cm −1 relates to A 1g modes of vibration. 78 Additionally, Figure 3g clearly illustrates the successful doping of magnesium ions in the SnS lattice, as sequential red shifts are seen with the introduction of the Mg element into the SnS framework. Further, no additional, unidentified peaks of the magnesium sulfide and sulfide phases were seen in the Raman spectra, indicating both the purity and the successful doping of Mg in the SnS lattice.…”

“…The Raman spectra of pure SnS and Mg–SnS with various levels of doping are shown in Figure g, where four main peaks are seen at 93, 232, 309, and 617 cm –1 . The broad peak at 617 cm –1 may be caused by the deformation mode of sulfate in SnS, while the Raman peaks at 93 and 232 cm –1 are attributed to transverse and longitudinal optical A g vibrational modes and 309 cm –1 relates to A 1g modes of vibration . Additionally, Figure g clearly illustrates the successful doping of magnesium ions in the SnS lattice, as sequential red shifts are seen with the introduction of the Mg element into the SnS framework.…”

“…In a similar fashion, the characteristic peaks of π-SnS correlate with the database of JCPDS card no. 77–3356, and the peaks at 26, 30.8, 31.9, 32.8, 44.2, 50.57, and 52.38° correspond to the (222), (400), (410), (440), (540), and (622) planes, respectively. As for β-SnS, the distinctive peaks at 26.5, 31.6, 39.2, 44.4, and 52.5° are indicative of the (021), (111), (131), (150), and (211) diffraction planes, respectively, which are in good agreement with data provided by JCPDS card no. 83–1758. A comparative table (Table ST1) has been given in the Supporting Information regarding the lattice parameters and interlayer spacing of the three phases corresponding to their major peaks.…”

“…Out of which, 4A g , 2B 1g , 4B 2g, and 2B 3g are identified to be the Raman active [41] modes, 7 modes correspond to the IR active (3B 1u , 1B 2u , 3B 3u ), and the remaining two modes are Raman inactive (2A u ) modes [42]. The Raman spectra of the prepared SnS thin films exhibit three prominent Raman modes of orthorhombic SnS around…”
