Claim 0:
1. An energy scattering layer, comprising:
a plurality of substantially-transparent non-layered particles wherein said substantially-transparent non-layered particles are characterized as having a diameter up to 25 microns; and
a substantially-transparent matrix material that fixes the particles in a layer arrangement to form an energy scattering layer,
the energy scattering layer having an energy-incident side,
the particles being fixed in the matrix material such that each particle of the plurality of substantially-transparent particles is separated from each adjacent particle by an interstitial void in a manner that causes the layer arrangement to
reflect substantially all of one or more selectable wavelengths of incident energy impinging on the energy scattering layer from the energy-incident side, and
pass other wavelengths of the incident energy through the energy scattering layer;

the one or more selectable wavelengths of incident energy being determined by a scattering of incident energy based on 1) size of the substantially-transparent particles, an index of refraction of the materials comprising the substantially-transparent particles, a material composition of the matrix material, a size of the interstitial voids between the substantially-transparent particles; and 2) a surface plasmon resonance of the energy scattering layer.
