  • Title: Sunlight-driving formation and characterization of size-controlled gold nanoparticles.
    Author: Luo Y.
    Journal: J Nanosci Nanotechnol; 2007 Feb; 7(2):708-11. PubMed ID: 17450819.
    Abstract:
    Exposing a sodium citrate-HAuCl4 aqueous solution to sunlight results in the formation of size-controlled, citrate-capped gold nanoparticles. The gold nanoparticles were characterized by UV-visible, transmission electron microscopy (TEM), scanning electron microcopy (SEM), and X-ray diffraction (XRD) spectroscopic methods. It provides a general methodology for the economic, convenient, mild preparation of citrate-capped noble metal nanoparticles.
