Synthesis, characterization and optical property of flower-like indium tin sulfide nanostructures

Abstract

We report a simple method for novel flower-like In₄SnS₈nanostructure synthesis. A flower-like In₄SnS₈nanostructure was synthesized via a one-pot hydrothermal route using the biomolecule L-cysteine as a sulfur source. The structure was characterized using X-ray powder diffraction (XRPD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), nitrogen adsorption analysis and photoluminescence spectra. This flower-like structure consists of crosslinked nanoflakes and possesses good thermostability and a high BET surface area. Photoluminescence (PL) characterization indicates that it has a blue light emission. This facile, environmental friendly, method can be extended to other ternary sulfides nanostructure syntheses.
