Повний текст джерелаAbstract: In recent years, two-dimensional (2D) perovskite materials have attracted considerable attention duo to their unique and excellent electronic and optical properties, which make them an extremely promising semiconductor for light-emitting and display applications. Furthermore, the nonmagnetic perovskite can be semi magnetic semiconductor by incorporating magnetic impurities into lattices of the host perovskite to introduce magnetic properties. The coexistence of both excellent optoelectronic and magnetic properties, makes semi magnetic 2D perovskite to be a considerably promising material for opto-spintronic semiconductor devices for information processing and communications.In this thesis, we explore the electronic and optical properties of 2D perovskites via magneto-optical spectroscopy. We start from performing magneto-photoluminescence (PL) and magneto-transmission measurements on CsPbBr3-based nanoplatelets with a different thickness of the lead-halide slab, ranging from 2 to 4 layers of lead-halide octahedral plane. By applying in-plane magnetic fields up to 65 T, the optically inactive dark excitonic state is brightened. This approach allows us to directly observe an improvement of the PL emission on the low-energy side of the PL spectrum, which indicates that the optically inactive dark excitonic state is the lowest-lying state in these nanoplatelets. Additionally, combining our magneto-PL and magneto-transmission results with theoretical predictions of the exciton fine structure splitting, we accurately determine the energy splitting between the dark and bright excitons. We demonstrate that indeed the dark-bright exciton splitting increases with decreasing layers of lead-halide octahedral plane. We also demonstrate that the efficient emission from these nanoplateltes is due to a phonon bottleneck effect, which significantly reduces the relaxation of the photo excited excitons to the optically inactive dark state.Finally, we investigate the electronic properties of Mn-doped 2D (PEA)2PbI4 perovskite via magneto-transmission spectroscopy for various Mn molar fractions. We find that the exciton Lande g-factor can be controlled by the incorporated Mn concentration. With increasing Mn concentration x from 0 to 2%, the g-factor increases, which we attribute to the sp-d exchange interaction between band-edge excitons and spins hosted in Mn ions. If the Mn concentration is increased further, up to 5%, the exciton g-factor decreases. This anomalous counter-trend is attributed to the Mn-Mn interactions, which result in an effective anti-ferromagnetic coupling
