摘要：

Triplet excitons at the anthracene 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.
