Introduction

Single-walled carbon nanotubes (single-waledcarbonnanotubes, SWCNT) band gap fluorescence phenomenon of low-dimensional materials unique e-Statement Structure characterization provides a new method. This method can give semiconducting SWNTs chiral index contained in the sample and their Relative integrated intensity of photoluminescence. According to photoluminescence section information, you can get a sample estimate semiconducting single-walled carbon different chirality The relative concentration of quality nanotubes. Near infrared semiconductor single-walled carbon nanotubes Photoluminescence spectrum characterization methods
