摘要：
A facile synthetic method for monodisperse copper nanoparticles (CuNPs) has been reported, in which sodium hyposulphite works as reducing agent and gelatin serves as capping agent. Water-dispersed CuNPs have been produced without any protective atmosphere at room temperature. The as-prepared samples are characterized by ultraviolet-visible spectroscopy, transmission electron microscopy, X-ray diffraction and Raman spectra. The results show that the quasi-spheres and phase-pure crystalline CuNPs with a diameter of 32 +/- 3 nm can be quickly obtained by adjusting the amount of NaOH solution and quantity of gelatin. The present work suggests a great potential of using obtained CuNPs colloidal as an efficient substrate for surface-enhanced Raman scattering signals. (C) 2014 Elsevier B.V. All rights reserved.
