Patent ID: 8659822

Claim:
A multilayered infrared light reflective structure, comprising: a transparent substrate; a doped oxide film disposed on the transparent substrate, wherein the doped oxide film comprises a lithium and fluorine co-doped tin oxide (Li—F:SnO 2 ) film or a gallium-doped zinc oxide (Ga:ZnO 2 ) film; an oxide isolated layer disposed on the doped oxide film, thereby allowing incident light to be incident from a top surface of the transparent substrate into the multilayered infrared light reflective structure, wherein the oxide isolated layer comprises a tungsten oxide (WO 3-x ) layer; an oxide distributed Bragg reflector film sandwiched between the doped oxide film and the oxide isolated layer, wherein the oxide distributed Bragg reflector film is formed by laminating a plurality of pairs of oxide films, and wherein each of the pairs of oxide films comprises a lower TiO 2 film and an upper SiO 2 film.
