The TEM analysis confirmed the spherical shape of Au NPs with a diameter of 17-30 nm. The XRD analysis revealed that the Au NPs exhibited fcc crystal structure with an average crystallite...

The biosynthesized Au and Ag NPs were characterized by UV-visible spectroscopy (UV-vis), Fourier transform infrared spectroscopy (FTIR), powder X-ray diffraction analysis (XRD) and transmission...

Crystalline nanoparticles represented by four peaks corresponding to standard Bragg reflections (111), (200), (220), and (311) of face centers cubic lattice. The intense peak at 38.1 represents...

2019年7月23日 · Powder X-ray diffraction (XRD) is a common characterization technique for nanoscale materials. Analysis of a sample by powder XRD provides important information that is complementary to various microscopic and spectroscopic methods, such as phase identification, sample purity, crystallite size, and, in some cases, morphology.

2018年2月6日 · We succeed in selectively synthesizing fcc and hcp AuRu solid-solution alloy NPs at the Au/Ru ratio of 1:3. The structures of the obtained NPs are investigated using synchrotron powder X-ray...

2025年3月29日 · XRD analysis explored the crystal structures of porous silicon (Psi) alongside gold electrodes as components of Au/Psi/Au solar cells.
