The future of optics heavily relies on reliably and easy-to-fabricate plasmonic materials that allow for the manufacturing of novel and versatile products and devices. Nanorod arrays (NRA), for instance, are fabricated by anodising aluminium thin films with acidic solutions [1]. However, large scale manufacturing of such structures so far has mostly shown not to be very reliable and reproducible [2].
We present an easy-to-use protocol [3] that firstly allows for the reliable substrate-bound anodisation of aluminium thin films and subsequent pore filling of anodised alumina matrices, while secondly easily promoting the NRA integration into mechanically flexible plasmonic devices. Replacing the template with an elastic material yields a novel, flexible and mechanically stretchable plasmonic composite, which allows for reproducible spectral tunability in the visible wavelength range [4].
