Synthesis and characterization of SnSe 2 hexagonal nanoflakes

Abstract

Single phase SnSe 2 was synthesized at 180 °C by hydrothermal co-reduction method from SnCl 2·2H 2O== and SeO 2, its morphology and growth direction were investigated. The products were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM) and field emission scanning electron microscope (FESEM). Experimental results show that, the SnSe 2 powder almost consists of regular and homogenous hexagonal nanoflakes which grow along (0001) crystal plane, these nanoflakes are about 600–700 nm in side length and 30–40 nm in thickness.
