Abstract

We report a facile chemical route for the synthesis of monodisperse nanocrystals of various metal sulfides (PbS, Cu(2)S, and Ag(2)S) and their assemblies into nanocrystal superlattices (NCSs); the sulfides NCSs were precipitated by adding ethanol to nanocrystal colloids, which were obtained directly by a reaction between metal thiolate and thioacetamide in a pure dodecanethiol solvent.

摘要

我们报道了一种简便的化学路线，用于合成各种金属硫化物（硫化铅、硫化亚铜和硫化银）的单分散纳米晶体，并将它们组装成纳米晶体超晶格（NCSs）；通过向纳米晶体胶体中加入乙醇来沉淀硫化物NCSs，这些胶体是通过金属硫醇盐和硫代乙酰胺在纯十二烷硫醇溶剂中直接反应获得的。
