Prompt and delayed emissions from a naphthalene crystal doped with pyrene have been investigated in the temperature range 77-300 K. It is shown that delayed fluorescence (DF) in this crystal originates from heterofusion and homofusion of two different types of trap triplets at low temperature (T< 13
Triplet escitons at the nnthracene crystal surface yielded a hole photocurrent which was diffusion controlled concerning the excitons at high concentration of the oxidant. Similarities were found in hole photocurrents involving directly excited triplet excitons and in methylene blue sensitized ones.
