Abstract
A process for fabricating a structural color having ultraviolet reflectance is provided. The process includes providing an atomizing nozzle, a first nanoparticle solution and a second nanoparticle solution. The atomizing nozzle is used to spray a plurality of first nanoparticle solution layers, the plurality of first nanoparticle layers forming a low index of refraction stack. In some instances, a polymer solution can be sprayed before and/or after the spraying of each first nanoparticle solution layer. The atomizing nozzle is also used to spray a plurality of second nanoparticle solution layers, the plurality of second nanoparticle layers form a high index of refraction stack. Similar to the first nanoparticle solution layers, a polymer solution can be sprayed before and/or after the spraying of each second nanoparticle solution layer.
