Abstract

The rate constants of triplet-triplet annihilation were measured in anthracene single crystals with various degrees of damage. It was found that, as with the single-excitonic triplet decay rate, the double-excitonic triplet decay rate is severely affected by the presence of crystal defects. The experimental results were analyzed kinetically in the framework of triplet exciton trapping at crystal defects.
