Article Preview

Reversible photostructural conversions (darkening and bleaching) attended by a shift of transmittance edge and by the photoluminescence fatigue effect are revealed. Upon mechanical treatment of crystals the maximum of the luminescence excitation spectrum shifts toward higher energies. The low-energy edge of the luminescence spectrum flattens, and emission intensity increases. The experimental results are interpreted within a configuration model of two stable structural states of molecular groups.
