Kucherenko M.G., Palem A.A. ANNIHILATION DEPOLARIZATION OF FLUORESCENCE OF CENTRAL-FORMED MOLECULAR PROBES IN MICROPORES AND NANOPORES WITH LIQUID-CRYSTALLINE FILLER [№ 9 ' 2008] Kinetics of depolarization of fluorescence of molecular centers in spherical pores filled with nematic fraction which molecules orient phosphor dipoles along the normal line to this area of surface have been examined. Fluorescence anisotropy disintegration owing to multiple annihilation of stimulation which is carried out distantly, but taking into account stimulation migration within the system of accidentally distributed centers has been studied. It is shown that temporary dependence of anisotropy relates to the radius of pores and considerably differs for micro- and nanostructures.
Kucherenko M.G., Palem A.A. ANISOTROPY KINETICS OF PAIRED MOLECULAR BORES LUMINESCENCE AT CRYSTALLINE LIQUID NANO-DROPS [№ 6 ' 2007] Kinetics of degree changes of sensitized luminescence polarization of molecular centers interstitial at spherical nano-pores, filled up with nematic liquid crystal with homeotropical texture is researched in this article. The case of selective impact activation of radially built two-component system of luminophors with line polarized light with following distance nonradiating passing of energy of electron excitation to p-type molecules is regarded here. Also the theoretical model of the process at conditions of excitation migration absence at n-type centers and at its presence is constructed. Temporary dependences of sensitized luminescence anisotropy from the radius of nano-pores, speed of festers transfer and other parameters are got in this work.
Levshin L.V., Saletsky A.M., Kucherenko M.G., Palem A.A. LUMINESCENCE DEPOLARIZATION OF WELL-ORDERED MOLECULAR AGGREGATES [№ 1 ' 2005] Peculiarities of researches of local and aeolotropic systems on the base of polarization characteristics of its luminescence are shortly discussed in this article. Matematical model of luminescence depolarization process of well-ordered molecular associats (type J-aggregates) or mesomorphic domains, considering its rotation and paired annihilation of electronic excitation in limits of micro blast furnaces, is constructed. The cases of migration rapid annihilation of triplet excitons and static distance response of singlet and triplet excitons, are researched in ditail.
