Abstract
A multi-layer photonic structure may include alternating layers of high index material and low index material having a form [H(LH)] where, H is a layer of high index material, L is a layer of low index material and N is a number of pairs of layers of high index material and layers of low index material. N may be an integer≧1. The low index dielectric material may have an index of refraction nfrom about 1.3 to about 2.5. The high index dielectric material may have an index of refraction nfrom about 1.8 to about 3.5, wherein n>nand the multi-layer photonic structure comprises a reflectivity band of greater than about 200 nm for light having angles of incidence from about 0 degrees to about 80 degrees relative to the multi-layer photonic structure. The multi-layer photonic structure may be incorporated into a paint or coating system thereby forming an omni-directional reflective paint or coating.
