Evolution of the pentacene exciton band width in pentacene–tetracene blends
The Journal of Chemical PhysicsPentacene is one of the most investigated organic semiconductors. It is well known that the motion of excitons in pentacene and other organic semiconductors is determined by inter-molecular exciton coupling based on charge-transfer processes. In the present study, we demonstrate the impact of the admixture of tetracene, which has a larger band gap and ...
