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

Resumo

It has been revealed that a sensitized luminescence of AntAcBF₂ is observed in the boron difluoride dibenzoylmethanate (DBMBF₂)–boron difluoride anthracenoylacetonate (AntAcBF₂) system in the polystyrene matrix. The emission mechanism of energy transfer from DBMBF₂ to AntAcBF₂ has been established. The luminescence properties of bilayer films with one layer containing DBMBF₂ and another one containing AntAcBF₂ have been investigated. At luminophore contents in equimolar quantities, one observes a white luminescence of the bilayer polymer composite.
