Abstract

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.
