Highly-photoluminescent ZnSe nanocrystals via a non-injection-based approach with precursor reactivity elevated by a secondary phosphine

摘要

Highly-photoluminescent ZnSe quantum dots with 72% quantum yield and 22 nm full width at half maximum were synthesized with more reactive precursors via a non-injection approach with high synthetic reproducibility; ~(31)P NMR provided insight into the formation mechanisms of ZnSe monomers. Efforts on the development of synthetic approaches to colloidal semiconductor quantum dots (QDs) with high quality have been driven mainly by their technological potential.
