Abstract

Quantum efficiency η was determined for the fluorescence emitted from six dye vapors. The rate constants of the quenching of the fluorescence of POPOP, PPF, and PT vapors by oxygen were determined. The addition of a buffer gas (SF6) to POPOP vapor increased the efficiency η. The mechanism of quenching of the triplet POPOP molecules by the dye itself was analyzed.
