Phys. Rev. Lett. 77, 4820–4823 (1996)Theory of Exciton Migration and Field-Induced Dissociation in Conjugated PolymersReceived 19 June 1996; published in the issue dated 2 December 1996 The interplay of migration, recombination, and dissociation of excitons in disordered media is studied theoretically in the low temperature regime. An exact expression for the photoluminescence spectrum is obtained. The theory is applied to describe the electric field-induced photoluminescence-quenching experiments by Kersting et al. [Phys. Rev. Lett. 73, 1440 (1994)] and Deussen et al. [Synth. Met. 73, 123 (1995)] on conjugated polymer systems. Good agreement with experiment is obtained using an on-chain dissociation mechanism, which implies a separation of the electron-hole pair along the polymer chain. © 1996 The American Physical Society URL:
