Abstract in another language
A review is presented about sensitized luminescence and luminescence lineshape studies on pure and doped sodium nitrite which have led to detailed knowledge about the lowest excited states of this system. Both the lowest triplet state and the first excited singlet state are Frenkel excitons, states that can migrate through the crystal. This migration is appropriately described by a one-dimensional energy transfer process for the triplet and, surprisingly, also for the singlet state. The exciton states themselves show an evolution in time that reveal the transition from coherent to incoherent behaviour with increasing temperature. In combination with theoretical investigations a consistent picture of the exciton states in sodium nitrite is achieved.
