Flexible Multilayer Plasmonic Films for Biosensing and Photoemitting Applications.

ABSTRACT: Flexible plasmon metasensor devices describe the use of multiple Ag/Al₂O₃/mica layers for tunable plasmonic resonances and are a promising research direction. Here, we report on a flexible Ag/Al₂O₃/mica multilayer platform and its excellent performance on flexible biosensors and photon-emitting devices. In our approach, muscovite (mica) was adopted as a single-crystal substrate due to its optical transparency and mechanical flexibility. The Ag/Al₂O₃/mica multilayer film is characterized by X-ray diffraction and transmission electron microscopy. Optical, plasmonic, and biosensing studies of Ag/Al₂O₃/mica multilayers are performed for detailed understanding. A combination of optical absorption, numerical
