Synthesis and assembly of monodisperse spherical Cu2S nanocrystals

---

Abstract.
High-quality monodisperse Cu2S nanocrystals (sizes from 2 nm to 20 nm) have been successfully
synthesized by the reaction of copper stearate (CuSt2) and dodecanethiol (DDT) in 1-octadecene (ODE).
The nanocrystals were characterized using X-ray diffraction (XRD), X-ray photoelectron spectrum (XPS),
and transmission electron microscopy (TEM). These as-prepared Cu2S nanocrystals with certain sizes have
been found with good self-assembly behaviors, and they were easily to assemble into two-dimensional
and three-dimensional superlattice structures. DDT served as both sulfur source and capping ligand, and
was found a key factor to affect the growth and the self-assembly behaviors of the Cu2S nanocrystals.
