WebInterestingly, phosphorescence comes solely from the phenothiazine segment. Experimental results indicate that bridged counterparts of dibenzothiophene, dibenzofuran, and carbazole contribute as close-lying triplet states with locally excited (LE) character. WebBy aggregating certain fluorescent dye molecules, one can improve the energy matches between excited singlet and triplet states so as to promote the intersystem crossing (ISC) … WebApr 1, 2012 · Highlights. Fluorescence, excitation and sensitized phosphorescence excitation spectra of three fluoropyridine vapors were measured. The S 1 → T 1 intersystem crossing yields were determined by a sensitized phosphorescence method. Main nonradiative process is shown to be the S 1 → S 0 internal conversion.
