Kucherenko M.G., Dyusembaev R.N. DOUBLE-PULSE LASER ACTIVATION OF ORGANIC MOLECULES AND THEIR REACTION IN POLYMEROUS MATRIXES Kinetics of phosphorescence and delayed fluorescence of xanthene dyes (eosin, erythrozonus) in polymer films at systems irradiation with two impulses of different duration (50 mks and 15 ns) with arbitrary interval between the moment of the beginning of their generalization with lasers (IAG: Nd3+) with diode and lamp pumping, is researched in this article. Time-solved signals of examples’ glowing in different conditions of double-step activation are registered. The authors suggest theoretical model of forming of luminescent response of system on given time regime of its photoexcitation, taking into account the origin of interparticle correlation in spatial allocation of interacting molecules. Migration-accelerated coupled annihilation of triplet electronic excitation – as key element of kinetic scheme was taken into calculation. Numeral appraisals of typical parameters of reaction, progressed at metathetical-resonance mechanism were made in this article.
