Organic Vapour Fluorescence Following Excitation into High Electronic Triplet States

The fluorescence of anthracene vapors and its derivatives initiated by triplet-triplet excitation is observed. The quantum yield of inverce intersystem crossing of anthracene molecules is estimated (10 −2 ). The fluorescence initiated by triplet excitation is quenched by foreign pentane gas, thus pe...

Zusammenfassung:The fluorescence of anthracene vapors and its derivatives initiated by triplet-triplet excitation is observed. The quantum yield of inverce intersystem crossing of anthracene molecules is estimated (10 −2 ). The fluorescence initiated by triplet excitation is quenched by foreign pentane gas, thus permitting an estimation of the lifetime of highly excited triplet molecules.
