Anthracene-sensitized long-delayed rhodamine C fluorescence of the Langmuir-Blodgett films

Abstract

Results of investigation into the triplet-triplet energy transfer from a vacuum-deposited anthracene film to the Langmuir-Blodgett rhodamine dye film are presented. It is demonstrated that the observed long-delayed sensitized dye fluorescence is caused by annihilation of migrating triplet excitons.
