N2 - The polarized emission of colloidal quantum dots from II–VI and
perovskite semiconductors were investigated thoroughly, revealing
information about the optical transitions in these materials and their
potential use in various opto-electronic or spintronic applications. The
studies included recording of the micro-photoluminescence of individual
nanostructures at cryogenic temperatures, with or without the influence
of an external magnetic field. The experimental conditions enabled
detection of circular and/or linear polarized emission to elucidate the
exciton manifolds, angular momentum of the emitting states, Landé
g-factors, single exciton and bi-exciton binding energies, the
excitons’ effective Bohr radii, and the unique influence of the
Rashba effect. The study advances the understanding of other phenomena
such as electron–hole dissociation, long diffusion lengths, and
spin coherence, facilitating appropriate design of optical and
spin-based devices.
