WebDiamond Identification. Figure 1. A schematic of the model for each color state of a chameleon diamond based on absorption from valence band states to the proposed acceptor state being blocked by full compensation (the “yellow” state) or incomplete compensation when exposed to room lighting (the “green” state). WebDiamond is transparent from the UV (225 nm) to the far infrared. Only minor absorption bands exist resulting from two-phonon absorption between 2.5 and 6.5 µm. This makes diamond an ideal material for multispectral optical applications. Diamond’s optical properties are isotropic with an index of refraction of 2.4 in the visible region.
