中文摘要：

完成银硫化物的形成的更好的控制( Ag 2 S ) nanoparticles ， ultrasmall Ag nanoclusters 由 thiolate ligands 保护了( Ag 44(SR)30和 Ag 16(GSH)9)被用作先锋，它经由精细的化学，能乐意地被变换成 monodisperse Ag 2有可控制的尺寸( 4-16 nm )和可切换的溶剂亲密关系的 S nanoparticles (在水、器官的溶剂之间)。这个新合成协议使用原子 monodispersity 和 Ag nanoclusters 和一个新奇二阶段的协议图案的富有的表面化学，它为 Ag 2 S nanoparticles。

英文摘要：

To achieve better control of the formation of silver sulfide （Ag2S） nanoparticles, ultrasmall Ag nanoclusters protected by thiolate ligands （Ag44（SR）30 and Agla（GSH）9） are used as precursors, which, via delicate chemistry, can be readily converted to monodisperse Ag2S nanoparticles with controllable sizes （4-16 nm） and switchable solvent affinity （between aqueous and organic solvents）. This new synthetic protocol makes use of the atomic monodispersity and rich surface chemistry of Ag nanoclusters and a novel two-phase protocol design, which results in a well-controlled reaction environment for the formation of Ag2S nanopartides.
