As a result, readers obtain a balanced view of charge and exciton transport, covering such characterization techniques as spectroscopy and current measurements together with quantitative models.
oAbsorption of a photon in a pentacene semiconductor creates an excited electron-hole pair called an exciton.
The UV-vis spectrum of PAn exhibits two absorption peaks at 331 and 639 nm, which are due to the [pi]-[pi]* transition of the benzenoid ring and the exciton absorption of the quinoid ring, respectively [27, 28].
Specific topics include the exciton dispersion law and states of bimolecular thin films, the synthesis and properties of magnetic nanoparticles, the flowability of electrolyte copper powder, the photoluminescence of laser-synthesized anatase titanium dioxide nanopowders, examining cross-linked polyvinylpyridine in open reactors, the static and fatigue failure of bi-directional composite pipes, and the radio-protective efficiency of fullerenol in irradiated mice.
328 and 610 nm, representing the [pi]-[pi]* transition in the benzenoid structure and the exciton formation in the quinonoid rings, respectively.

One is due to a [pi]-[pi]* transition of the benzenoid ring at 345 nm, and two absorption peaks at 425 and 470 nm are due to exciton transitions.
The absorption spectra of EB films before irradiation show two absorption peaks at around 325 nm and 620 nm, which are due to [pi]-[pi]* transition of the benzenoid rings and the exciton absorption of the quinoid rings, respectively, as expected of PANI in the EB state (31).
