title: Synthesis of Ag nanoclusters by a pH-dependent etching method in aqueous solution.
abstract: We developed a pH-dependent etching method for the synthesis of stable fluorescent silver nanoclusters (AgNCs) in aqueous solution. The AgNCs emit at 530 nm when excited at 380 nm and can be used for Hg(2+) detection with a low detection limit and high selectivity.
