Abstract
As an emanating layered metal dichalcogenides (LMDs), tin disulfide (SnS2) has immense potentials in next generation nanodevices considering their facile synthesis and versatile attributes. Here, we describe the hydrothermal synthesis of SnS2 nanoparticles at different temperatures and growth times and discussed its structural, optical and magnetic characteristics in detail. The SnS2 nanoparticles displayed growth time dependent structural, optical and magnetic properties. The structural analysis displayed hexagonal phase of SnS2 nanoparticles whose thickness increase with duration of growth. The vibrational modes of SnS2 nanoparticles in Raman spectra exhibited an increase in intensity with growth time, indicating an increased layer thickness with growth time. In addition, the optical properties were also affected by the growth time. Moreover, excitation dependent photoluminescence emission from these nanoparticles is observed, which is attributed to the polydispersity of nanoparticles. The realisation of room temperature ferromagnetism makes it a promising material for spintronic applications. Photocurrent properties of the spin coated n-SnS2 on p-silicon were analysed by studying J-V relationships. Tunable optical, electrical and magnetic properties of SnS2 layers could capacitate a great deal of freedom in modelling atomically thin optoelectronic and spintronic devices.
