Article on "Gallium–a versatile element for tuning the photoluminescence properties of InP quantum dots" by Wegner, K. D., Pouget, S., Ling, W. L., Carrière, M., & Reiss, P. (2019).
Abstract
With the goal to tune the emission properties of colloidal InP quantum dots, the incorporation of Ga was explored. Unexpectedly, depending on the nature of the gallium precursor, the photoluminescence shifted either to the red (gallium oleate) or to the blue (gallium acetylacetonate). In the first case, larger-sized InP/GaP core/shell nanocrystals were formed, while in the second case the formation of an InGaP alloy structure enabled the blue range of emission (475 nm) to be accessed.
