在这项工作中，我们证明了单壁碳纳米管（SWNT）的传播表面等离子体激元（SPP）耦合光致发光（PL）激发。spp从单独标记的SWNT发射到几微米处，并记录等离子体耦合PL以确定该远程平面寻址方案的效率。效率取决于以下因素：(i) SPP发射场与SWNT位置之间的纵向和横向距离；（ii） SWNT相对于等离子体传播波矢量（k(SPP)）的方向。我们的实验探索了碳纳米管在等离子体和纳米光子器件中作为等离子体传感器的可能性。
In this work, we demonstrate propagating surface plasmon polariton (SPP) coupled photoluminescence (PL) excitation of single-walled carbon nanotube (SWNT). SPPs were launched at a few micrometers from individually marked SWNT, and plasmon-coupled PL was recorded to determine the efficiency of this remote in-plane addressing scheme. The efficiency depends upon the following factors: (i) longitudinal and transverse distances between the SPP launching site and the location of the SWNT and (ii) orientation of the SWNT with respect to the plasmon propagation wave vector (k(SPP)). Our experiment explores the possible integration of carbon nanotubes as a plasmon sensor in plasmonic and nanophotonic devices.
