Phase-Selective Synthesis of Zn 3 Sb 2 and ZnSb Quantum Dots via Temperature-Controlled Zn-Loss-Mediated Reconstructions

QDs to thermodynamically more stable ZnSb QDs. This phase-transition behavior and the associated electronic structure provide important insights into phase stability and composition control strategies in Zn-Sb nanocrystals. Moreover, the broad NIR absorption, narrow band gaps, and facile composition/phase tunability of Sb-based group II-V Zn-Sb QDs suggest that they are promising low-toxicity material platforms for energy and optoelectronic applications such as NIR photodetectors, solar cells, and thermoelectric devices.
