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. © Owned by the authors, published by EDP Sciences, 2013.
