ABSTRACT:
Transparent heat-mirrors are disclosed which are formed from tin-doped indium oxide films or antimony-doped tin oxide films deposited onto polymeric substrates. Low temperature deposition processes, such as ion-beam sputtering, are employed to preserve the polymeric substrates, and films having high transparency to visible radiation and high reflectivity to infrared radiation are deposited on the polymeric substrates by carefully controlling the partial pressure of oxygen during deposition.
