Dispersion techniques for single-walled carbon nanotubes (SWNTs) are one of the fundamental and important issues. In this study, the optical properties of SWNT dispersed with a coconut detergent made from plants derived from Southeast Asia were evaluated by photoluminescence (PL) measurement. As a result, when the SWNT suspensions were diluted with a phosphate buffer solution that doesn’t contain a detergent, it was clarified that SWNT dispersed with coconut detergent has a more stable PL than that with sodium dodecyl sulfate (SDS) which is commonly used.
