Aluminum-Enhanced Fluorescence of Cu8 Nanoclusters: An Effective Method for Sensitive Detection of Fluoride in Aqueous and Bioimaging

Abstract: Here, we report glutathione-protected water-soluble copper nanoclusters (Cu8 NCs) with excellent properties of high stability, large Stokes shift, and low toxicity. The molecular formula and structure of the Cu8 NCs were confirmed through good agreement between spectroscopic results and theoretical calculations. The origin of optical properties and chemical stability of the Cu8 NCs was determined through natural bond orbital analysis combined with time-dependent density functional theory calculations. It was f… Show more
