Single Step Laser-Induced Deposition of Plasmonic Au, Ag, Pt Mono-, Bi- and Tri-Metallic Nanoparticles

“…One can see that monometallic NPs demonstrated characteristic peaks corresponding to localized surface plasmon resonance. Positions of the observed LSPR peaks are 440, 560, and 220 nm for Ag, Au, and Pt NPs, correspondingly, which coincide with previously reported literature data [ 34 , 35 , 36 ]. The absorption spectrum of trimetallic Au-Ag-Pt NPs displayed two separated LSPR peaks with maxima at 230 and 530 nm.…”

Laser-Induced Deposition of Plasmonic Ag and Pt Nanoparticles, and Periodic Arrays

“…Absorption spectra of NPs from Pt-containing precursors (Figure 8b) demonstrate more specific features, especially for the solution of C8H18OPtSi2. One can see pronounced peaks at 220 and 260 nm, which are attributed to the intra-band electronic transitions from energy states of (n = 5; l = 2) and (n = 6; l = 0) to higher energy states of the conduction bands of Pt NPs [37,38]. Pt NPs obtained from (C8H12)Cl2Pt precursor display a wide absorption band centered at about 270 nm.…”

Simulation and Synthesis of Cobalt (Co) Nanoparticles by Gamma Radiation Technique

“…Among these techniques, the gamma irradiation method presents some advantages over conventional methods. It is an uncomplicated process that provides fully reduced and very pure metal nanoparticles which are free from other products or reducing agents [ 42 , 43 , 44 , 45 , 46 ].…”
