“…Strong and sharp peaks appear in the spectrum at 560 and 1384 cm -1 which are due to the characteristics of SnS. These bands are similar in positions, if compared with that obtained by Khel [42] and Henry [43]. The band at 1659 cm -1 is assigned to H-O-H bending of H 2 O molecules [44].…”

SnS films have been prepared by electrodeposition technique onto Cu and ITO substrates using acidic solutions containing tin chloride and sodium thiosulfate with sodium citrate as an additive. The effects of sodium citrate on the electrochemical behavior of electrolyte bath containing tin chloride and sodium thiosulfate were investigated by cyclic voltammetry and chronoamperometry techniques. Deposited films were characterized by XRD, FTIR, SEM, optical, photoelectrochemical, and electrical measurements. XRD data showed that deposited SnS with sodium citrate on both substrates were polycrystalline with orthorhombic structures and preferential orientations along (111) directions. However, SnS films with sodium citrate on Cu substrate exhibited a good crystalline structure if compared with that deposited on ITO substrates. FTIR results confirmed the presence of SnS films at peaks 1384 and 560 cm-1. SEM images revealed that SnS with sodium citrate on Cu substrate are well covered with a smooth and uniform surface morphology than deposited on ITO substrate. The direct band gap of the films is about 1.3 eV. p-type semiconductor conduction of SnS was confirmed by photoelectrochemical and Hall Effect measurements. Electrical properties of SnS films showed a low electrical resistivity of 30 Ω cm, carrier concentration of 2.6 × 10

“…The XRD diffraction peaks at 26.03° to 66.04° for SnS with Miller indices of (201), (210), (111), (301), (311), (511), (610) and (512), respectively, in agreement with the SnS nanocrystals literature (Kumar et al 2014;Kafashan et al 2017;Oda et al 2014). On the other hand less prominent peak was observed at 2θ = 34.5° which corresponds to the (1 1 1) reflection plane has compare to the report by Henry et al (2013) with prominent peak. The narrow peaks indicate nano-size particles that are just above the quantum dots size range.…”

Optical and structural-chemistry of SnS nanocrystals prepared by thermal decomposition of bis(N-di-isopropyl-N-octyl dithiocarbamato)tin(II) complex for promising materials in solar cell applications

Mixed ligand precursor complex bis(N-di-isopropyl-N-octyl dithiocarbamato)tin(II) complex was synthesized from its respective dithiocarbamate ligands, characterized and thermalized through thermogravimetric analysis to yield tin sulfide (SnS) nanocrystals. The thermal decomposition pattern was recorded as a function of the required temperature for the formation of the SnS nanocrystals at 360 °C. The SnS nanocrystals were characterized using optical, vibrational, structural and morphological analyses instruments. The obtained orthorhombic phase SnS nanocrystals showed indirect and direct optical energy band gaps close to the 1.5 eV of the bulk SnS.

“…Therefore, the following general trend is observed during these treatments: smaller grains tend to grow in bigger size and decrease the film porosity by filling up of voids, improvement in the crystallinity and change in the band gap occurred after thermal treatment [32].…”
