In this work, we demonstrate that a preferential Ga-for-Zn cation exchange is responsible for the increase in photoluminescence that is observed when gallium oleate is added to InZnP alloy QDs. By exposing InZnP QDs with varying Zn/In ratios to gallium oleate and monitoring their optical properties, composition, and size, we conclude that Ga<sup>3+</sup> preferentially replaces Zn<sup>2+</sup>, leading to the formation of InZnP/InGaP core/graded-shell QDs. This cation exchange reaction results i ...[more]
