To benefit from plasmon-derived phenomena we also increased the loading of CNFs with AuNRs to 19.6 wt%. We observed that this results in a lower experiment resolution (Figure ) due to significant overlap of the π→π * band of a photochrome with the extinction of Au-1-CNFs framework. Moreover, increased loading contributes to faster composite sedimentation and randomizes its macroscopic behaviour. These aspects make consecutive spectroscopic experiments less comparable and require proper data treatment and new experimental design. We substantially reduced the influence of sedimentation by correcting spectra to keep material's isosbestic point (296 nm) and, where necessary, increased the number of repetitions. Moreover, we also designed an OFF-ON experimental approach for hybrid Azo-Au systems (vide infra).
