摘要：

A red-shift and broadening of the emission of the BIC J-aggregate in glass were observed at low temperatures (4.5 K). To explain the observation a transformation of the excess excitation energy in the bath with disordering of the structure of molecular aggregate is proposed. The characteristic time of this energy transformation is 315 ps at 4.5 K for an excess energy of 400 cm-1. Another possible mechanism of exciton self-trapping by exciton-phonon interaction is discussed.
