Theoretical Comparison of Optical and Photothermal Properties of Near-Infrared Plasmonic Nanoparticles

Liu K., Xue X., Furlani E.P., University at Buffalo, US

In this presentation, we use 3D computational models to compare the optical and photothermal behavior of plasmonic nanostructures that are commonly used for near-infrared (NIR) applications. These include SiO2@Au core-shell, Au nanocage and Au nanorod [...]

Self-Assembly and Optical Behavior of Magnetic-Plasmonic Nanostructures

Liu K., Xue X., Sukhotskiy V., Furlani E.P., University at Buffalo, US

We introduce a bottom-up method for the fabrication of nanostructured photonic media and demonstrate proof-of-principle using a multiphysics modeling approach. The method involves magnetic field-directed self-assembly of magnetic-plasmonic core-shell particles (e.g. Fe3O4@Au) into extended particle [...]
