[Influences of terraazaindene on absorption spec tra and fluorescence spectra of sensitizing dyes].
This study is about the influences of tetraazaindene (TAI) on absorption spectra and the fluorescence spectra of three kinds of sensitizing dyes. The absorption of all peaks of the dyes enhance with increasing TAI, among which the absorption of J-aggregate has even marked enhancement. At certain value of TAI, the absorption of monomolecule of dye enhances much more rapidly as well as the absorption of H-aggegte decreasing because of H-aggregate dissociating into monomolecules. The results obtained also show that the fluorescence emissions of the dyes enhance with increasing TAI. The mechnisms of the observed phenomena are discussed in detail.
