Abstract
A method which utilizes photon counting is developed for measuring low-level luminescence lifetimes. The technique requires two counters and a pulse sequence generator. The method is applied to the measurement of the delayed fluorescence lifetimes in anthracene and tetracene single crystals. The lifetime of triplet excitons in vapor-grown tetracene crystals is found to be 43 μsec.
