[0091] Mixing sensitivity--The mixing for CdSe experiments was done offline by mixing the Cd and Se precursors in a three-neck flask; subsequently, the experiment was conducted by using a syringe pump to pump the mixture. For this synthesis, the reactants appear to have minimal sensitivity to mixing time at room temperature; spectra of a Cd+Se reagent mixture left overnight at room temperature yielded no fluorescence or particle formation. Based on this result, mixing could be done on a larger scale over the course of hours, simplifying reactor design and minimizing the need for microscale inline mixers. Cold offline mixing appears equivalent to cold inline mixing, allowing for the heating up method where the premixed reactants are rapidly heated to the reaction temperature.
