Synthesis of Dual Red‐Emitting Fluorescent Silver Nanoclusters in Aqueous Lipoic Acid‐Based Polymer Solutions and Application for Cu2+ Detection and Cell Imaging

Abstract: Dual red‐emitting fluorescent and water‐soluble silver nanoclusters (AgNCs) were synthesized in aqueous solutions through the reduce reaction method using lipoic acid‐modified‐poly(vinyl alcohol) as a novel protective ligand and sodium borohydride as a reducing agent. The obtained AgNCs exhibited a large Stokes shift and high stability. The fluorescence lifetime of the obtained AgNCs was 1.4×104 ns and the corresponding quantum yield reached 7.1 %. The obtained AgNCs showed highly sensitive and selective detec… Show more
