 Abstract: From liquid solutions of aromatic hydrocarbons in alkanes three types of delayed luminescence (DL) can be observed: delayed monomer fluorescence, delayed excimer fluorescence and phosphorescence from the aromatic hydrocarbon. According to Lim and co-workers a fourth type of DL (DL4) from solutions of naphthalene and di-α-naphthylalkanes in isooctane can be assigned to the phosphorescence from intermolecular and intramolecular triplet excimers. However, the DL4 band is absent in the DL spectrum of a carefully prepared solution of naphthalene in isooctane at 293 K. From the spectral and kinetic data it follows that DL4 is the sensitized phosphorescence from strongly phosphorescent impurities similar to diacetyl.
