在这项贡献中，我们应用了一种微观技术，该技术依赖于激光照射的尖锐金属尖端附近的增强电场，作为高度受限的光源。针尖用于局部激发沉积在玻璃上的单壁碳纳米管(SWNT)的光学响应。我们展示了同样的单壁碳纳米管的光致发光和拉曼成像，其空间分辨率约为10 nm。(C)2006爱思唯尔B.V.保留所有权利。
In this contribution, we apply a microscopic technique that relies on the enhanced electric field near a sharp, laser-irradiated metal tip that acts as a highly confined light source. The tip is used for the local excitation of the optical response of single-walled carbon nanotubes (SWNT) deposited on glass. We demonstrate photoluminescence and Raman imaging of the same SWNTs with a spatial resolution of about 10 nm. (c) 2006 Elsevier B.V. All rights reserved.
