The light-controlled ?uorescence molecular switch was prepared
with Au nanoclusters and thiolated spiropyran dyes. Its ?uorescence
can be reversibly modulated using UV/Visible light due to ?uores-
cence resonance energy transfer (FRET) from the Au NCs to the
open-ring state merocyanine of the spiropyran molecules.
