Abstract:

We developed a new chemical strategy to enhance the stability of lead selenide nanocrystals (PbSe NCs) against oxidation, through the surface passivation by P-O- moieties. In the synthesis of PbSe NCs, tris(diethylamino)phosphine (TDP)-selenide (Se) was used as a Se precursor, and the resulting PbSe NCs withstood long-term air exposure wh...More
