In article number 1701763 , Yuebing Zheng and co‐workers report how intersystem crossing (ISC) controls plasmon‐enhanced fluorescence in hybrid systems of plasmonic nanostructures and spiropyran molecules. They further demonstrate An all‐optical switching of the plasmon‐enhanced fluorescence is demonstrated by irradiating the hybrid systems with alternative UV and green light, which modulates the ISC process via the molecular isomerization. The ISC‐mediated plasmon‐enhanced fluorescence paves a new way toward optical modulators, optical switches, biosensing and bioimaging.
