Graphical abstract: The Cu{sub 2}Se nanoparticles were synthesized by a simple and rapid method at room temperature. The TEM and SEM images show that the Cu{sub 2}Se nanoparticles were spherical. Highlights: Black-Right-Pointing-Pointer Cu{sub 2}Se nanoparticles were synthesized by the reaction of nanoSe{sup 0} sol with Cu{sup +} ions. Black-Right-Pointing-Pointer The Cu{sub 2}Se nanoparticles were spherical with cubic structure and well crystallized. Black-Right-Pointing-Pointer Optical and electrochemical properties of Cu{sub 2}Se nanoparticles were observed. Black-Right-Pointing-Pointer The formation mechanism of Cu{sub 2}Se nanoparticles was proposed. -- Abstract: A simple and rapid method has been developed to synthesize cuprous selenide (Cu{sub 2}Se) nanoparticles by the reaction of selenium nanoparticles sol with copper sulfate solution containing ascorbic acid at room temperature. Cu{sub 2}Se nanoparticles were characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), and energy dispersive X-ray analysis (EDX). The results indicated that Cu{sub 2}Se nanoparticles were cubic crystal structure and spherical with the diameter about 75 nm. The ultraviolet-visible absorption spectrum (UV-vis) and cyclic voltammetry of Cu{sub 2}Se nanoparticles were also investigated. The optical band gap energy of Cu{sub 2}Se nanoparticles was 1.94 eV. On the basis of a series of experiments and characterizations, the formation mechanism of Cu{sub 2}Se nanoparticles was discussed.
