Sustainable Synthesis of InP Quantum Dots via Rieke-Indium Reduction: Size Control and Ensemble Optical Properties.

ABSTRACT: The aminophosphane-based synthesis of InP quantum dots (QDs) suffers from a significant drawback due to its low atomic efficiency, resulting in the production of three equiv of phosphonium salts as a byproduct for each equivalent of phosphorus atom incorporated into InP QDs. To address this limitation, we propose a novel synthetic approach for the fabrication of InP-QDs, utilizing Rieke-In (In*) as both an indium precursor and a simultaneous reducing agent for the aminophosphanes employed. This method not only enables a more efficient and sustainable synthesis of InP-QDs but also offers excellent size tunability, as demonstrated by the successful synthesis of green-emitting InP/GaP/ZnS-QDs. The observed remarkable emission quantum yield (QY) exceeding 40% and a narrow full-width at half-ma
