Room-temperature synthesis of nanocrystalline Ag2S and its nanocomposites with gold.
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.
