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).
37 eV at room temperature [25, 26], and has a strong excitonic
emission in the ultraviolet range even at room temperature due to its larger excitonic
binding energy of 60 meV which is significantly larger than other materials .
The absorption band is characteristic of the high-level excitonic
excitation absorption of a semiconductor, clearly showing the successful deposition of Pb-Sb-S QDs on the ZnO surface.

This transition is an intrinsic feature of the wurtzite ZnO and has its origin in the excitonic
More than one types of metal and organic ions will be introduced in the perovskite structure to realize layered materials which are expected to exhibit both excitonic
and free carrier behavior with enhanced stability.

states transitions, respectively [22, 23].
It also discusses excitonic
quasimolecules in nanosystems, and excitons formed from a spatially separated electron and hole in dielectric quantum dots.
Awarded under QNRF's National Priorities Research Programme - Exceptional Proposals (NPRP-EP), the project entitled 'Coherent Energy Transfer in Novel Excitonic
Materials for Solar Energy Applications' provides an innovative solution to the global question of energy harvesting.
It has a relatively benign chemical nature, a deep excitonic
energy level, and a direct bandgap of ~ 3.
