Citation Structural Investigation and Optical Properties of Silver Nanoparticles Synthesis by Chemical Method [Текст] / J. Singh, J. Tripathi, M. Sharma [et al.] // Журнал нано- та електронної фізики. – 2020. – Т. 12, № 2. – 02006. – DOI: 10.21272/jnep.12(2).02006.
Abstract We reported here the synthesis, structural characterization and optical properties of silver nanoparticles (Ag NPs). Chemical synthesis method was used to synthesize the Ag NPs. Ethylene was used as capping and reducing reagent. As prepared Ag NPs sample was characterized by X-ray diffraction, X-ray absorption spectroscopy (XAS), scanning electron microscope (SEM) and fourier transform infrared spectroscopy (FTIR). Rietveld refinement of diffraction data revealed the dimensions of unit cell, hkl values, and Fm-3m space group of Ag NPs. The average crystallite size was found to be ~ 38.5 nm. Both X-ray absorption near edge structure (XANES) and Extended X-ray absorption fine structure (EXAFS) techniques at silver K-edge at BL-9 beam line at Indus-2 synchrotron radiation source (2.5 GeV, 125 mA), RRCAT, Indore (M. P.), India. A computer software package IFEFFIT was used to analyze physical parameters. FTIR revealed chemical bonding and symmetry of molecules.
