Ultrafast Surface-Plasmon Enhancement of Exciton and Defect Luminescence in ZnO Thin Films
Abstract
Femtosecond pump-probe and photoluminescence measurements in transmission and reflection show that ultraviolet band-edge and visible defect luminescence in ZnO films can be selectively enhanced by coupling to Ag surface-plasmon polaritons or localized surface plasmon resonances.
