Abstract

Fluorescence and reflectance spectra of dipolar N,N-dimethylaminobenzylidene 1,3-indandione (DMABI) molecular crystals of α and β crystallographic modifications have been studied over a wide temperature range. The luminescence spectral properties have been discussed by means of the self-trapped exciton model. The crystal phase transition in both α and β modifications resulting in the deeply-trapped excitonic state formation has been observed at low temperatures, below 60 K.
