Synthesis, thermal stability and structural transition of cubic SnS nanoparticles

Synthesis and Characterization of π-SnS Nanoparticles and Corresponding Thin Films

“…Thus, the annealing of the π-SnS thin film improved the grain quality and grain size, suggesting that the grains obtained enough thermal energy to enable effective film growth. The same trend in grain growth with annealing temperature has also been reported previously [7]. morphology and no noticeable holes or cracks.…”

“…Semiconducting metal chalcogenide nanoparticles have attracted research attention owing to their tunable absorption properties for photovoltaic and hydrogen production applications [1][2][3][4][5][6]. In particular, there has been an increasing demand for tin sulfide (SnS) nanoparticles in recent years as photovoltaic materials [3], lithium battery anode materials, and photocatalytic materials owing to their favorable optoelectrical properties, which can be easily altered by manipulating the synthesis conditions [7].…”

Real-time monitoring of phase transitions in π-SnS nanoparticles

“…Such behaviour is in line with the phase diagram of SnS, where α is the stable phase at room temperature, and β is the high-temperature phase of SnS. 34 This result also agrees with the findings of Hegde et al , 27 where after heating π-SnS nanoparticles capped with triethanolamine, the α phase is observed upon cooling to room temperature. Moreover, the observed phase transition is accompanied by a shape distortion of the SnS nanoparticles.…”

“…30 In a recent study, Hegde et al investigated the thermal stability of π-SnS. 27 The triethanolamine capped cubic phase nanoparticles, 300–400 nm in size, were reported to remain structurally stable up to 400 °C under vacuum for one hour, whereas annealing at 450 °C and 500 °C leads to partial and complete transformation to the orthorhombic α-SnS phase, respectively. 27…”

Growth-control of hexagonal CdS-decorated ZnO nanorod arrays with low-temperature preheating treatment for improved properties and efficient photoelectrochemical applications

“…An annealing atmosphere of 600 °C may have been extreme for CdS-sensitized ZnO heterostructures in this study when considering the evaporation temperature of Cd (500 °C) and S (600 °C) elements. 37,38 Fig. 6d and e shows the transmission electron microscope (TEM) and high-resolution TEM (HRTEM) images of ZnO/CdS annealed at 500 °C.…”
