This manuscript demonstrates a room-temperature synthesis for Ag2S nanocrystals and their nanocompsites with Au and the Au could be deposited only at a single site on each Ag2S seed nanocrystal, where in contrast, Ag2S could grow homogeneously on Au seed nanocrystals, resulting in core-shell Au@Ag2S nanoparticles, which still possessed the optical properties of Au nanocrystals; this facile synthesis could be employed towards fabricating a variety of nanocomposites with interesting structures and tailored functionalities.
本手稿展示了一种室温合成硫化银纳米晶体及其与金的纳米复合材料的方法，金只能沉积在每个硫化银种子纳米晶体的单个位点上，相比之下，硫化银可以在金种子纳米晶体上均匀生长，从而形成核壳结构的金@硫化银纳米颗粒，该颗粒仍具有金纳米晶体的光学性质；这种简便的合成方法可用于制备具有有趣结构和定制功能的各种纳米复合材料。
