Abstract
- Emission spectroscopy is performed to study the optical transitions between electronic bands of SWCNs formed in <f>AlPO4−5</f> (AFI) crystal. Strong visible emission is observed under laser light illumination at room temperature. The emission is excited by the light polarized along the <f>c</f>-axis and its polarization is also along this direction. On the other hand, non-linear emission is observed under the resonant excitation of the lowest absorption band of SWCNs. The emission is excited by the light polarized along the <f>c</f>-axis, but it shows the polarization perpendicular to the <f>c</f>-axis. The polarization character is discussed on the basis of the selection rules of the optical transitions predicted by the full line-group symmetry of SWCNs. [Copyright &y& Elsevier]
