Abstract
Provided are nanoparticles passivated with a cationic metal-chalcogenide complex (MCC) and a method of preparing the same. A passivated nanoparticle includes: a core nanoparticle; and a cationic metal-chalcogenide compound (MCC) fixed on a surface of the core nanoparticle.
Claims4
A passivated nanoparticle comprising:
- a core nanoparticle;
- and
- a cationic metal-chalcogenide which passivates the core nanoparticle,
- wherein the cationic metal-chalcogenide is fixed on a surface of the core nanoparticle, and
- wherein the cationic metal-chalcogenide is selected from the group consisting of Zn2S2, Zn—Se—Se—Zn, Zn2Te2, Cu2S2, Cu2Se2, Cu2Te2, Mn2S2, Mn2Se2, Mn2Te2, Fe2S2, Fe2Se2, Fe2Te2, Co2S2, Co2Se2, Co2Te2, and mixtures thereof.
