The CdSe-ZnS core-shell QDs used in this study were grown (in two steps) via reduction of organometallic precursors at high temperature. The growth medium consisted of coordinating solution containing a small fraction of n-hexylphosphonic acid in a mixture of n-trioctyl phosphine (TOP), n-trioctyl phosphine oxide (TOPO), and alkylamines. Core growth was then followed by overcoating with a few monolayers of ZnS. 46 (link), 47 , 48 (link), 49 , 50

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
