Here, a multi-scale modeling approach is employed to determine optimal conditions for optical hydrogen sensing using the Pd-Au-H system. Changes in hydrogen pressure translate to changes in hydrogen content and eventually the optical spectrum. At the single particle level, the shift of the plasmon peak position with hydrogen concentration (i.e., the \"optical\" sensitivity) is approximately constant at 180 nm/c_H for nanodisk diameters >~ 100 nm. For smaller particles, the optical sensitivity is negative and increa","authors_text":"J. Magnus Rahm, Maria Bancerek, Paul Erhart, Pernilla Ekborg-Tanner, Tomasz J. Antosiewicz, Tuomas P.
