## Abstract Monomeric carbazole derivatives show phosphorescence in the wavelength region between 400 and 500 nm. Poly(vinyl carbazole) (PVCA) in dilute frozen solutions also shows phosphorescence in this region and, in addition, delayed fluorescence owing to tripletโtriplet annihilation. The latte
## Abstract It has been demonstrated that the triplet lifetime of nonemitting molecules in the dilute vapor phase โ even for complex triplet decays โ can be accurately determined by means of timeโresolved tripletโtriplet (TโT) energy transfer to a strong emitter molecule. Besides the test molecules
