X-ray diffraction (XRD) analysis confirmed the crystalline nature of the AgNPs, revealing distinct diffraction peaks at specific 2θ angles (38.2°, 44.3°, 64.5°, and 77.4°)...

XRD spectra of green-prepared Ag NPs and Ag/RGO NCs are given in Figure 3A. (222), respectively, for the Ag/RGO NCs, which occurs with the face-centred cubic structure of metallic Ag (JCPDS...

Abstract− Silver nanoparticles were synthesized by micro emulsion route in W/S ratio of 5 at room temperature. X-ray diffraction (XRD) pattern reveals FCC structure of Ag nanoparticles. Spherical shape of Ag nanoparticles of average particle size 5.0 to 12.0 nm were observed by transmission electron microscopy.

A facile and green strategy is reported here to synthesize gold (Au), silver (Ag) and gold–silver (Au–Ag) alloy nanoparticles (NPs) through bio-reduction reactions of aqueous corresponding ...

2012年12月5日 · Namely, silver–gold alloy and core(Ag)–shell(Au) type nanoparticles were synthesized at various Ag/Au ratios using only sodium citrate as reductant without any stabilizers. The synthesized NPs were characterized by different structure analysis methods.

The crystal structure of Ag nanoparticles has been examined by X-ray diffraction (XRD Shimadzu model 6000, Shimadzu, Tokyo, Japan) using Cu Kα (0.154 nm) as an X-ray source to generate diffraction patterns from the crystalline samples at ambient …

2019年12月1日 · Microstructure of the multilayer was characterized by XRD θ /2 θ scan and φ -scan analysis, depth-resolved XPS analysis, and Doppler broadening of annihilation radiation (DBAR) spectra of positron measurements. The experimental results indicate that, at Tsub = 25 °C, the Ag deposition forms Ag/SiO 2 /Si multilayer structure.

Ag is Copper structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. Ag is bonded to twelve equivalent Ag atoms to form a mixture of corner, edge, and face-sharing AgAg12 cuboctahedra. All Ag–Ag bond lengths are 2.94 Å.

2024年3月18日 · The X-ray diffraction (XRD) analysis results in the crystalline nature of Ag NPs having nearer dodecahedron structure. The parameters including micro-strain, internal stress and energy density have been estimated for all reflection peaks of XRD.

2012年1月1日 · This study has shown that thermally evaporated Ag thin films neither too thin (ultra-thin) nor too thick (foil)—50 and 130 nm thick films used here—are ideal for investigating surface modification by a simple iodization procedure for less than ∼15 min. XRD, optical, AFM have helped track the interesting changes such as appearance of ...
