In-situ SAXS Probing Evolution of Precursor and Onset of Nucleation of ZnSe Colloidal Semiconductor Quantum Dots

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 low temperature 40 °C via the equilibrium of SeTOP + HPPh2 ↔ SePPh2H + TOP.
