  • Method and apparatus for producing near-infrared radiation
    Publication number: 20020197050
    Abstract: The subject invention pertains to a method, apparatus, and composition of matter for producing near-infrared (near-IR) radiation. The subject invention can incorporate a polymer and a metal-containing compound, wherein the metal-containing compound can incorporate a metal-ligand complex, wherein when the metal-ligand complex becomes excited, energy is transferred from the ligand to the metal, wherein, the energy transferred to the metal by sensitization is emitted as near-infrared radiation. In a specific embodiment, the subject invention relates to a composition of matter having a luminescent polymer and a metal containing compound where the metal containing compound incorporates a metal-ligand complex such that the absorption spectrum of the metal-ligand complex at least partially overlaps with the emission spectrum of the luminescent polymer.
