Abstract

Optical properties of metal nanoparticles, especially gold nanorods in this review, are investigated by static and dynamic near-field microscopy and spectroscopy. We describe instrumentation for the dynamic near-field spectroscopy which enables less than 100-fs temporal resolution at the tip of the apertured near-field probe. We show that wavefunctions of the plasmon modes resonant with the incident light are imaged by near-field transmission imaging as well as by near-field two-photon induced photoluminescence measurements. We also show the results of the ultrafast near-field imaging of gold nanorods, where the dynamics after photoexcitation strongly depends on the position on the nanorod.
