Light emitting polymers singlet exciton yield

W. Barford, Theory of singlet exciton yield in light-emitting polymers, Phys. Rev. B 70... 

Finally, we remark that this chapter has focussed on excitons confined to single chains. However, the formalism can easily be extended to interacting chains, and this will be considered briefly in Section 9.6 when we describe a theory for the singlet exciton yield in light emitting polymers. 

In the final section of this Chapter we discuss the singlet exciton yield in light emitting polymers obtained via charge injection. As we now show, this yield is a key a factor in the electroluminescence efficiency of polymer light emitting devices.
