n.
An electrically neutral excited state of an insulator or semiconductor, often regarded as a bound state of an electron and a hole.

The luminescence at 450 nm excited in the region near the edge of the intrinsic absorption of the host material, whose intensity is strongly increased at low temperature, can be attributed to excitonic emission (luminescence of self-trapped excitons or near-defect self-trapped excitons).
The 2D excitons are created in suspended semiconductor nanoplates with a thickness below 5 nm, and transition-metal dichalcogenide monolayers.
This would ensure a reasonable Voc, as well as permitting a good dissociation and difficult recombination of excitons.
It should also be noted that excitons with higher energies may be the source of the superior PC activity observed for this material.
It also discusses excitonic quasimolecules in nanosystems, and excitons formed from a spatially separated electron and hole in dielectric quantum dots.
We also include the effect of excitons for which we solve Bethe-Salpeter Equation.
The dynamics of excitons in CdSe QDs were studied using temperature dependent photoluminescence (PL) in the range from 17-300 K.
In the process, each single photon or particle of sunlight that is absorbed potentially creates multiple packets of energy called excitons.
In addition to an established exciton dissociation at the central donor-acceptor interface, the excitons generated in the outer acceptor layer of this new OPV are first relayed by energy transfer to the central acceptor, and subsequently dissociated at the donor interface.
There are several ways to confine excitons in semiconductors, resulting in different methods to produce quantum dots.
It was shown that the ground state and the low lying levels of such a sphere can he described in terms of excitons which describe the rotation and the deformation of the spheres.
