Title: Subwavelength coatings and methods for making and using same

Patent ·
OSTI ID:1345379
;

Methods are disclosed for forming subwavelength coatings for use in the UV, visible, or infrared part of the electromagnetic spectrum. A first material and a second material are deposited onto a substrate. The first material may include dielectric spheres of subwavelength size that self-assemble on the substrate to form a template or scaffold with subwavelength size voids between the spheres into which the second material is deposited or filled. First and second materials are heated on the substrate at a preselected temperature to form the subwavelength coating.
