    Experimental and Numerical Investigation on Plasmonic Properties of Single-Sprouted Potato-Shaped Au-Ag Bimetallic Nanoparticles

    Herein, we report the experimental and theoretical study on scattering spectra of single-sprouted potato-shaped Au-Ag bimetallic nanoparticles. In detail, first, the sprouted potato-shaped nanoparticles are sy...

    Effect of Size-Dependent Dam** on Plasmon-Hybridized Modes of Asymmetric Nanosphere Dimers: the Role of Nanogap, Size Ratio, Surrounding Medium, and Substrate

    Herein, we report quasi-static theory-based simulations on size-asymmetric Au and Ag nanosphere dimers in which size-dependent dam** induced by the electron-surface interaction is prominent. The sensitivity ...

    Optical Properties of Au-Ag Bimetallic Nanoparticles of Different Shapes for Making Efficient Bimetallic-Photonic Whispering Gallery Mode Hybrid Microresonators

    For the first time, we propose a bimetallic-photonic whispering gallery mode (WGM) hybrid microresonator for the detection and sizing of single protein molecules in real time. To optimize the sensitivity of hy...
