계면활성제를 이용한 단층 탄소나노튜브 분리에 따른 라만과 Photoluminescence 연구 = Raman and Photoluminescence Study of Single-Walled Carbon Nanotubes Dispersed in Sodium Dodecyl Sulfate Aqueous Solution Using Ultrasonication

다국어 초록 (Multilingual Abstract)

We have studied, using Raman and photoluminescence (PL) spectroscopy, material property changes of single-walled carbon nanotubes (SWCNTs) dispersed in sodium dodecyl sulfate(SDS) aqueous solution by ultrasonication. Radial breathing mode Raman intensities of the dispersed SWCNTs shows different behavior depending on their chiralities as the sonication time increases. As the amount of SWCNTs dispersed in 1wt% SDS solution increases, both a downshift of the G-band Raman frequency and an enhancement in the PL intensity were observed.
