Abstract

Excitation profiles and time characteristics of luminescence from the self-trapped exciton (STE) have been measured on the quasi-1D halogen-bridged metal complexes having degenerate and nondegenerate CDW ground states. From the comparison of the excitation profiles of the STE luminescence with those of the gap states, it was demonstrated that excitons are converted to spin-soliton pairs. This conversion occurs from the STE through a finite potential barrier, magnitude of which strongly depends on the degeneracy of CDW.
