Deep-red ( λ em ∼ 710 nm) thiolated Ag@Au nanoclusters with a quantum yield of ∼18% were rapidly (∼12 min) prepared in aqueous solutions. The effects of pH and silver ions were demonstrated. The surface modification further resulted in nanoclusters with a quantum yield of ∼38%, the highest value ever reported for water-soluble red Au nanoclusters. This will highly facilitate their applications in sensing, bioimaging, etc.
