Temperature dependence of the intensity of slowed-down fluorescence for aromatic compounds in n-paraffin matrices

  • Published:
Russian Physics Journal Aims and scope

Temperature dependence of the intensity of annihilation slowed-down fluorescence is studied for aromatic molecules in frozen n-paraffin solutions. With increasing temperature, regions with increased slowed-down fluorescence intensity are established for molecules expelled to the surface of small crystals of the solvent in the process of its freezing. It is assumed that this effect is caused by the increasing number of annihilating pairs involved in slowed-down fluorescence emission. The number of annihilating pairs increases due to rotation of pairs of triplet molecules with parallel directions of magnetic moments in the position with antiparallel direction of the magnetic moments.
