The electronic structure of conjugated polymer semiconductors reflects the complex interplay between intrinsic rr-electron delocalization along the polymer backbone and strong electron-phonon coupling, and the existence of energetic and positional disorder in solution-processed thin films. In a hypothetical, infinitely straight polymer chain, the highest occupied molecular orbital (HOMO) and lowest unoccupied...

Polymer semiconductors often have a semicrystaDine structure due to their relatively rigid jtlamellar crystals observed in the crystallization of typical insulating polymers such as polyethylene, Jt-conjugated polymer semiconductors generally tend to crystallize into ID nanostructures, such as nanowires this is induced by both an attractive n-n...

There are many type of emitters gas phase atoms and ions molecules in the gas, solution, or solid phase metal ions as an integral part of a solid state lattice energy traps or activator sites, which may be a specific ion or site defect, in a semiconductor or other sohd conjugated polymers semiconductors as either a solid, or as a colloidal dispersion in some other medium or solution and hot metals. In aU but the latter three cases emission is from a locahsed emitter, with both states involved in the transition localised in a small region of space, on an atom, ion, or molecule. However, for semiconductors, some emissive polymers, and hot metals, the states involved in the transition extend across a relatively large region of space and a large number of atoms.
