Optical simulation results: (a) position-dependent absorption spectra within an active layer; depth corresponds to the distance from the interface between ETL and AL, (b) depth profile of exciton generation rates and a multilayer OSC structure (inset), and (c) the comparison of spectra of light...
Various efforts have been made to obtain nanodimensional particles according to the object of investigation. In the study of quantum size effect on excitons, which is one of the most attractive mesoscopic properties exhibited by nanodimensional particles, the particles are usually embedded in a glass...

If the pump pulse frequency corresponded to the Urbach tail of a glass sample, the carriers trapping and excitons formation was followed by the excitons absorption and excitation of conduction electrons. If a sample was illuminated at the red-edge of its Urbach tail, the photo-excitation ...
We demonstrate the importance of exciton-exciton annihilation at high injection densities and present evidence that this process produces photo-induced absorption (PA) through the generation of charges. We present a model which accounts for PA from both photoexcited singlet excitons and the charge ...
Introduction Lead sulfide (PbS) quantum dots (QDs) continue to be a material of large scientific and technological interest due their size-dependent optical properties. Above all, PbS QDs present a remarkably tunable optical absorption and luminescence from the visible to the near-infrared range. ...
