Abstract

In carbon nanotubes (CNTs), the excitons and phonons confined in the one-dimensional structure are strongly interacted each other, which has been observed as an intense resonant Raman scattering and phonon-assisted photoluminescence (PL) of the excitons [1]. Recently, we focus on the combination of photonic nanostructures and CNTs to enhance the Raman scattering and photon emission from the CNTs by a modified density of optical states [2,3]. In this study, first we have studied fundamental optical properties of our CNTs before device fabrication and observed a strong exciton-phonon interaction.
