Journal ArticleDOI
Near-Field Two-Photon-Induced Photoluminescence from Single Gold Nanorods and Imaging of Plasmon Modes
TL;DR: In this paper, the two-photon-induced photoluminescence properties of single gold nanorods were investigated by scanning near-field spectroscopy, and the process was found to be initiated by a sequential onephoton absorption for creating a pair of an electron and a hole in the sp and d bands.
Journal ArticleDOI
Plasmon mode imaging of single gold nanorods.
TL;DR: Two-photon-induced photoluminescence images and spectra of single gold nanorods are investigated by using an apertured scanning near-field optical microscope to reveal characteristic features reflecting an eigenfunction of a specific plasmon mode as well as electric field distributions around the nanorod.
Journal ArticleDOI
Near-field optical imaging of plasmon modes in gold nanorods.
TL;DR: Investigation of optical properties of single gold nanorods by using an apertured-type scanning near-field optical microscope shows several longitudinal surface plasmon resonances, well reproduced by calculated local density-of-states maps.
Journal ArticleDOI
Imaging of surface plasmon and ultrafast dynamics in gold nanorods by near-field microscopy
TL;DR: In this paper, the authors investigated the near-field optical properties of single gold nanorods and found that the behavior of the collective motion of electrons in the center of the rod is different from that in both ends.
Journal ArticleDOI
Photoluminescence from gold nanoplates induced by near-field two-photon absorption
TL;DR: In this article, the authors investigated two-photon induced photoluminescence (PL) properties of single gold nanoplates by using an apertured scanning near-field optical microscope.
