The study of morphology-controlled synthesis and the optical properties of CuSe nanoplates based on the hydrothermal method

In this study, CuSe nanoplates have been synthesized using copper sulfate and Se powder as the raw materials by a simple and rapid hydrothermal process. The edta disodium (EDTA) was used as the surface active agent to moderate the morphologies of CuSe nanoparticles. As-synthesized CuSe samples were successfully characterized by X-ray diffraction (XRD), X-ray energy dispersive spectroscope (EDS), scanning electron microscopy (SEM) and Raman spectrometer, UV-visible (UV-vis) spectroscopy and photoluminescence (PL). XRD analysis demonstrated the hexagonal klockmannite phase of CuSe nanoplates. The as-synthesized products were homogeneous and highly crystallized. The structural and compositional analysis revealed that the products were the pure phase of CuSe with corresponding atomic ratios. With sufficient reaction materials, the reaction time has an influence on the growth of large-scale CuSe nanoplates. CuSe nanoplates obtained by the described method could be a potential material in photoelectric device.
