In situ SAXS probing the evolution of the precursors and onset of nucleation of ZnSe colloidal semiconductor quantum dots

Author affiliations

Abstract

The whole evolution processes, from precursors to quantum dots (QDs), were in situ investigated by SAXS and UV-vis. Diphenylphosphine (HPPh2) accelerates the dissolution of zinc oleate lamellar mesophase in the presence of selenide tri-n-octylphosphine (SeTOP) at a low temperature of 40 °C via the equilibrium of SeTOP + HPPh2 ⇔ SePPh2H + TOP.
