Luminescence of a Polymer Composite Doped with Boron Chelates. Mechanism of Luminescence Sensitization

摘要

It has been revealed that a sensitized luminescence of AntAcBF(2) is observed in the boron difluoride dibenzoylmethanate (DBMBF2)-boron difluoride anthracenoylacetonate (AntAcBF(2)) system in the polystyrene matrix. The emission mechanism of energy transfer from DBMBF2 to AntAcBF(2) has been established. The luminescence properties of bilayer films with one layer containing DBMBF2 and another one containing AntAcBF(2) have been investigated. At luminophore contents in equimolar quantities, one observes a white luminescence of the bilayer polymer composite.
