摘要
Polarized light microscopy (PLM) is used to image individual single-walled carbon nanotubes (SWNTs) suspended in air across a slit opening. The imaging contrast relies on the strong optical anisotropy typical of SWNTs. We combine PLM with a tunable light source to enable hyperspectral excitation spectroscopy and nanotube chirality assignment. Comparison with fluorescence microscopy and spectroscopy confirms the assignment made with PLM. This represents a versatile new approach to imaging SWNTs and related structures.
极化的轻显微镜学(PLM ) 习惯于围单人赛的碳 nanotubes (SWNT ) 越过裂缝开始在空中推迟了的图象个人。成像对比依靠典型地代表 SWNT 的强壮的光 anisotropy。我们把 PLM 与悦耳的轻来源相结合启用 hyperspectral 刺激光谱学和 nanotube chirality 赋值。有荧光显微镜学和光谱学的比较证实与 PLM 做的任务。这代表一条万用的新途径到成像 SWNT 和相关结构。
