Variation in kinetics of the annihilation luminescence of dyes in polymers under pulsed laser excitation

Kinetics of delayed fluorescence caused by annihilation of the excited triplet (T) centers with migrating {sup 1}{Delta}{sub g}-excitations of molecular oxygen is studied. The system was additionally excited by the laser pulse depleting the population of T centers at the arbitrary moment t{sub 0}. The dependence of a response on a number of parameters characterizing the system and external action is studied. The manifestations of nonlinearity factors and interparticle correlations are separately examined.
