Аннотация

The temperature influence on an annihilation delayed fluorescence of aromatic molecules in Langmuir-Blodgett films was investigated. It is shown that the efficiency of migration of triplet excitons depends on temperature owing to inhomogeneous broadening of energetic levels caused by local inhomogeneity of film structure. From experimental data the quantities of scattering of Anthracene, 1,2-Benzanthracene and Fluoranthene triplet levels were determined. The influence of external magnetic field on delayed fluorescence characteristics was studied. On an incipient stage of luminescence decay the magnetic effect replicates that of crystals. In the course of time magnetic field effect on intensity of delayed fluorescence decreases.
