Anchoring copper nanoclusters to Zn-containing hydroxy double salt: construction of 2D surface confinement induced enhanced emission toward bio-enzyme sensing and light-emitting diode fabrication.

Surface CIEE based on Zn-HDS as host material and GSH-CuNCs as guest molecules was developed to produce fluorescence composite GSH-CuNCs/Zn-HDS for the first time. It displays high quantum yield, long fluorescence lifetime and good stability, and was applied to sensitive bioenzyme sensing and fabrication of a high performance light-emitting diode.
