In article number 1702990, Peer Fischer, Frank Neubrech, Na Liu, and co‐workers fabricate three‐dimensional palladium helices by nanoglancing angle deposition exhibiting strong circular dichroism for sensitive hydrogen detection in the flammable range. The linearity of the sensor response is significantly improved using palladiumgold hybrid helices. Such a chiral plasmonic sensor scheme is of potential...
In this article, a chiral plasmonic hydrogen‐sensing platform using palladium‐based nanohelices is demonstrated. Such 3D chiral nanostructures fabricated by nanoglancing angle deposition exhibit strong circular dichroism both experimentally and theoretically. The chiroptical properties of the palladium nanohelices are altered upon hydrogen uptake and sensitively depend on the hydrogen concentration...
