Quantum Dots Synthesis And Properties

Ag–Cu dendrites are grown from Cu foil/plate by a galvanic displacement reaction between AgNO3 aqueous solution and the Cu substrate at room temperature. The dendrites show increased surface-enhanced Raman spectroscopy (SERS) enhancement capability for the detection of organic dye molecules.
