Özet
Doping of colloidal quantum wells (CQWs) has emerged as an effective strategy for tailoring their optical, electronic, and magnetic properties. Incorporation of transition-metal and lanthanide ions can enhance photoluminescence quantum yields (PLQYs), introduce a large Stokes-shifted emission, and tune optical properties across visible and near-infrared (NIR) spectral regions. This review summarizes recent progress in the colloidal synthesis, photophysics, and applications of doped CQWs with a particular focus on Cu-, Ag-, Mn-, Hg-, and Yb-doped CQWs. Their distinct contributions to dopant-mediated emission, magneto-optical and spin-dependent phenomena, and long-wavelength optoelectronics are discussed. The review also examines the use of doped CQWs in light-emitting diodes (LEDs), multiexciton lasing, and Förster resonance energy transfer (FRET). Key challenges include controlling dopant concentration and spatial distribution, identifying dopant sites and oxidation states, clarifying dopant–host interactions, and developing reproducible synthesis and device-integration strategies. Progress in these areas will determine how effectively doped CQWs can be translated into optoelectronic, photonic, and energy-conversion technologies.
