Metal-organic decomposition inks offer a facile route for preparing functional nanoparticle and conductive coatings based on precursor and solvent-based methods. Using spray deposition as roll-to-roll compatible coating method [1], we investigated the spray deposition of the silver nitrate precursor and the subsequent transformation into metallic silver layers via thermal annealing in situ and in real-time. We employed a combination of surface sensitive time-resolved wide- and small-angle x-ray scattering and optical spectroscopy. Thus, we followed the nanostructuring and the transformation of the deposited precursor into deposited metallic silver nanoparticles and correlate the occurring plasmon resonance to the nanoparticulate layer morphology. This is indispensable for optimizing the coating by tuning the deposition and annealing parameters for future use as sensors [2]. [1] S. V. Roth, J. Phys.: Condens. Matter 28, 403003 (2016) [2] G.
