Elimination of gallium concentration on focused-ion-beam-fabricated Au/Ag nanorod surface to recover its Raman scattering characteristic

Nanoparticle coupling effect allows enhanced localized field on Au bowl-like pore arrays

“…The specic properties of the electromagnetic eld in ordered plasmonic arrays have recently attracted much attention owing to their applications in the physical and chemical arenas, [1][2][3][4][5][6][7][8] such as in photovoltaic devices, 1 nanoantennae, 2 subwavelength imaging, 3 analytical chemistry, 4 electrochemistry, 5 surface enhanced Raman scattering (SERS), 6 etc. Much research shows that ordered plasmonic arrays can be realized using photolithography, 9 wet and dry chemical etching, 10 and template methods.…”

AuGa2on focused Ga ion beam-fabricated Au nanorod array for trace detection of melamine cyanurate in milk solution

“…Notably, the sample with the high Ga ion energy has a relatively weak interaction (e.g., Ga ion implantation) with the Au surface owing to the low potential energy of the incident Ga ion, which may reduce the formation of AuGa 2 . 18) Figures S2(a The CV molecular probe was prepared in a dilute aqueous solution (10 ¹5 -10 ¹15 M). Raman spectra were obtained using a confocal microscopy Raman spectrometer (Renishaw inVia) with a He-Ne laser at 633 nm and a magnification of 50©.…”
