Formation of ZnO/ZnCdSe Alloy Quantum Dots in the Presence of High Oleylamine Contents.

To the best of our knowledge, this report presents, for the first time, the schematic of the possible chemical reaction for a one-pot synthesis of ZnCdSe alloy quantum dots (QDs) in the presence of low/high oleylamine (OLA) contents. For high OLA contents, high-resolution transmission electron microscopy (HRTEM) results showed that the average size of ZnCdSe increases significantly from 4 to 9 nm with an increasing OLA content from 4 to 10 mL. First, [Zn(OAc)]-OLA complex can be formed by a reaction between Zn(OAc) and OLA.
