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.

고립된 탄소나노튜브를 얻기 위해 계면활성제 Sodium Dodecyl Sulfate(SDS) 수용액에 단층 탄소나노튜브 분말을 넣어 초음파 처리를 하는 과정 중에 발생하는 물성 변화를 라만과 Photoluminescence를 통하여 연구하였다. 단층 탄소나노튜브(SWCNT) radial breathing mode(RBM)의 라만신호 세기의 변화는 SWCNT의 chirality에 따라 서로 다른 경향성을 보이고 초음파 처리 시간에 영향을 받음을 확인하였다. 또한 동일한 농도의 계면활성제에 담긴 SWCNT의 농도가 커지면 G-band 라만 진동수가 작아지면서 Photoluminescence 세기가 증가하는 현상을 관측하였다.
