- W2891322824 abstract "We report an effective method to produce surface-enhanced Raman scattering (SERS) substrates with improved enhancement efficiency, high uniformity, greater chemical and physical stability, and absolute synthetic reproducibility. Nanobipyramidal gold (Au) core and silver (Ag) shell nanorods (NRs) with variable length were prepared simply by varying the Ag precursor amount during growth, and we successfully prepared NRs of lengths from 200 to 1200 nm and studied their formation mechanism and morphology using transmission electron microscopy (TEM) and their optical properties by using UV–vis–near-IR (NIR) and Raman spectroscopy. Here we have utilized the properties of both Au and Ag nanoparticles by synthesizing Au@Ag core–shell NRs for high SERS enhancement. NRs have stronger absorption and large scattering cross sections for electromagnetic radiation, and variation of the aspect ratios of these NRs leads to a broad-band surface plasmon tuning in the vis–NIR region. The relative SERS enhancement efficiencies of these core–shell Au@Ag NRs have been measured by using 4-mercaptobenzoic acid (4-MBA), crystal violet, and 4-mercaptopyridine as Raman tags, and the obtained SERS results show their huge enhancement (∼1010 for 4-MBA), which was substantiated through finite-difference time-domain computer simulations. Our work shows superior SERS enhancement compared to the previously reported results for pure Au and Ag NRs and bimetallic NRs, with the Au core and Ag shell having an aspect ratio in the same range." @default.
