Optical orientation and alignment of excitons in ensembles of inorganic perovskite nanocrystals
M. O. Nestoklon, S. V. Goupalov, R. I. Dzhioev +12
We demonstrate the optical orientation and alignment of excitons in a two-dimensional layer of CsPbI perovskite nanocrystals prepared by colloidal synthesis and measure the ani…

Direct bandgap optical transitions in Si nanocrystals
A. A. Prokofiev, A. S. Moskalenko, I. N. Yassievich +5
The effect of quantum confinement on the direct bandgap of spherical Si nanocrystals has been modelled theoretically. We conclude that the energy of the direct bandgap at the -…

Energy transfer processes in Er-doped SiO2 sensitized with Si nanocrystals
I. Izeddin, D. Timmerman, T. Gregorkiewicz +4
We present a high-resolution photoluminescence study of Er-doped SiO2 sensitized with Si nanocrystals (Si NCs). Emission bands originating from recombination of excitons confined i…
