![]() Finally, the enhanced photothermal effect of 2−xS NRs has been demonstrated. The calculated coupled coefficients between SPR of the Cu 2−xS shell and LSPR of the Au NRs is 180 meV, which is much stronger than that of TSPR of Au NRs of 55 meV. Encapsulated Gold Core/Shell Nanostructures for the Sensitive and Selective Detection of Copper Ions Rui Hu, Taiki Furukawa. The dispersion properties of the coupling of 2−xS NRs with the LSPR of the initial Au core are studied experimentally by changing the length of the Au NRs, which are explained theoretically by the coupled harmonic oscillator model. The extinction spectrum of the 2−xS NRs with three coupled resonance peaks is simulated by using the FDTD method, taking into account the electron-transfer effect. particles to a solution containing the gold nanorods, they could attach to the gold. Iron Copper Gold Platinum Palladium Silver Core-Shell Nanoparticles: Product No: NRE-16048: CAS No. Although, for 2S NRs, only TSPR and LSPR peaks can be seen and a redshift arises with the increasing Cu 2S shell thickness, implying that no plasmonic coupling between Au NRs and Cu 2S shell occurred. nanoparticles, namely anisotropic silver-copper oxide core-shell. Iron Copper Gold Platinum Palladium Silver Core-Shell Nanoparticles Buy ultra-High-Purity Nanomaterial’s Worldwide Shipping Fast Delivery FedEx. ![]() With the Cu 2−xS shell increasing (fixed Au NRs), the TSPR peak slightly redshifts and the LSPR and SPR peaks blueshift, owing to competition between the redshift of the refractive index effect and blueshift from the plasmon coupled effect. The extinction spectrum of 2−xS NRs is dominated by the surface plasmon resonance (SPR) of the Cu 2−xS shell, the transverse surface plasmon resonance (TSPR), and the longitudinal surface plasmon resonance (LSPR) of the Au NRs. ![]() Dual plasmonic 2−xS core−shell nanorods (NRs) have been fabricated by using a hydrothermal method and plasmon-coupled effect between the Au core and Cu 2−xS shell in the near-infrared (NIR) region.
