Abstract

Indium phosphide is the most studied of the colloidal III-V QDs, with significant attention focused on the phosphorus source and/or reaction conditions to improve QD quality. Comparatively limited attention has been directed toward controlling the reactivity of the indium precursor. In this study we introduce an approach that utilizes recyclable triarylphosphine adducts of indium(III) chloride to selectively prepare InP QDs with absorption profiles spanning 419-620 nm. This control is achieved through careful choice of the triarylphosphine ligand, which changes the nature of the nucleation profile from continuous to burst.
