Organic-based hybrid devices received strong attention from both academy and industry because of their potential for low-cost production and flexible device applications [1]. Recently, the novel technique of airbrush spray deposition was used in the fabrication of organic-based multilayer devices such solar cells [2]. This technique allows for performing rapid deposition of organic-based nanostructured layers showing high homogeneity over a large area and is thus of great interest in industrial applications. We used Grazing Incidence Small Angle X-ray Scattering (GISAXS) to investigate the structure of a colloidal nanoparticle film deposited on a flat Si-substrate by using a commercial airbrush-spray. The study shows a strong dependence of the film homogeneity on the substrate-to-spray distance and the strong influence of the solvent choice on the film lateral ordering opening a promising route to generate laterally structured templates and scaffolds for the fabrication of ultrahigh-density media.
