Description
Summary:II–VI quantum dots (QDs) are of keen scientific interest due to their size-dependent optoelectronic properties, which make them viable candidates for a plethora of fields including biomedics, solar power, LEDs, electronic displays, and agriculture. Efforts to improve the effectiveness of QDs for these applications continue through the utilization of ligand exchanges, cation exchanges, and doping. Building upon these efforts and following the literature precedent of Sb-doped CdSe thin films, this paper presents the treatment of colloidal CdSe QDs with SbCl3 as a synthetic strategy for producing Sb-doped CdSe QDs. Finally, however, rather than self-limited exchange as predicted by the thin film work, a unique two-phase reaction is observed that yields ferroelectric particles.
