原始语种摘要: Herein, we report a facile one-pot method for the synthesis of orange/red-emitting fluorescent copper nanoclusters (Cu NCs), in which bovine serum albumin (BSA) served as the capping scaffold (Cu NCs@BSA) and hydroxylamine hydrochloride (NH2OH ⋅ HCl) as the reducing agent. To the best of our knowledge, this is the first time to adopt this mild reductant to synthesize fluorescent Cu NCs. The as-prepared Cu NCs@BSA exhibits strong orange or red fluorescence at room temperature depending on the synthesis process, and the maximum excitation and emission peaks were at 355 nm and 615 nm, 395 nm and 645 nm, respectively. Synthesis conditions including the amounts of NH2OH ⋅ HCl, the selection of reducing agent, the molar ratio of BSA/Cu(NO3)2, the pH...
