We have investigated two-photon-induced photoluminescence images and spectra of single gold nanorods by using an apertured scanning near-field optical microscope. The observed PL spectrum of single gold nanorod can be explained by the radiative recombination of the electron-hole pair near the X and L symmetry points. PL images reveal characteristic features reflecting an eigenfunction of a specific plasmon mode as well as electric field distributions around the nanorod.
我们使用带孔径的扫描近场光学显微镜研究了单个金纳米棒的双光子诱导光致发光图像和光谱。单个金纳米棒的观测光致发光光谱可以通过X和L对称点附近电子-空穴对的辐射复合来解释。光致发光图像揭示了反映特定等离子体模式本征函数以及纳米棒周围电场分布的特征。
