Abstract
A particle is provided that includes a first material and a second material, arranged to provide a Fano resonance effect, for example in the visible portion of electromagnetic spectrum. The first and second materials may be substantially clear in the visible portion of the electromagnetic spectrum. The first material may include an inorganic material, such as SiO, TiO, HfO, ZrO, diamond, or a combination thereof. The second material may include a polymer. The first material has a first refractive index and the second material has a second refractive index, where the first refractive index and second refractive index have a difference of 0.5 or greater, and 1.0 or less. The first material may form a core and the second material may form a shell surrounding the core. Alternatively, the first and second materials may form a Janus particle, an asymmetric dimer, or an aggregate.
