Fig. 7From: Facile Synthesis of Monodisperse Gold Nanocrystals Using Virola oleifera Powder X-ray diffraction pattern for a gold nanoparticle prepared with 2 mL of Virola oleifera extract over 20 min. Broad peaks were observed and are characteristic of nanocrystals. The Au 111 peak at 38.1° was very intense due to the orientation of the AuBack to article page
