Abstract
Reversible photostructural conversions (darkening and bleaching) atten ded by a shift of the 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, a nd emission intensity increases. The experimental results are interpre ted within a configuration model of two stable structural states of mo lecular groups.
