Open Air Synthesis And Stability Analysis Of Air-Stable PBSE Quantom Dots
Air-stable lead selenide quantum dots were synthesized with a simple PbCl2-oleylamine system in open air,
using selenium dissolved in 1-octadecene as Se precursor. The as-synthesized PbSe quantum dots were air-stable and their
air stability was confirmed by a systematic study with transmission electron microscopy. The protection shields formed by
chloride anions, oleylamine, and organic and inorganic hybrid were discussed.
