报告简介：

In this presentation, the syntheses of colloidal gold nanocrystals and their pla**onic properties and applications would be described. Gold nanospheres, nanorods and nanobipyramids with narrow size distributions were obtained by seed-mediated growth method. In addition, fine size tuning was achieved through mild oxidation and anisotropic overgrowth, which allows for precise control of the pla**on resonance energies, affording attractive pla**onic features, including their tunable pla**on wavelengths over a wide spectral range, extremely large absorption/scattering cross-sections, and large enhancements of local electric fields and densities of photonic states. Finally, pla**onic applications of the as-prepared gold nanocrystals were described. Examples will include active pla**on switching, pla**onic catalysis, pla**onic sensing, time-temperature indicators and local photothermal heating.
