Abstract: A scalable method of fabricating large area nanoparticle arrays is disclosed. The method uses a combination of nanofabrication and additive manufacturing techniques to fabricate ordered nanoparticle arrays on wide number of substrates, including flexible substrates. Nanosphere lithography may be used to form a monolayer of polymer nanospheres. A metal may be deposited on the nanospheres, using a physical vapor deposition technique. The nanoparticles may then be decomposed using intense pulsed light technique. Ordered nanoparticle arrays have several promising applications, for example, thin films with tailored light scattering signatures, sensors based on surface-enhanced Raman scattering, nanostructured electrode arrays, and ordered catalytic islands for nanostructure growth.
