| Abstract: | In this paper we investigate the effect of intershell coupling effect to nonlinear photoluminescence in multiwalled carbon nanotubes. We employ the tight-binding model. The intershell coupling reduces the bandgap and electron transition probability, thus we explain why it is difficult to observe luminescence from multiwalled carbon nanotubes. |
