Abstract
Transparent heat‐mirror films of TiO2/Ag/TiO2 on glass with a visible transmission of 84% (at 0.5 μm) and an infrared reflectivity of 98–99% (at 10 μm) have been fabricated by rf sputtering. Initial tests indicate that the films are thermally stable in air at 200°C and inert to water attack. Because of their excellent optical properties and apparent stability, these transparent heat‐mirror films offer great promise for use in solar‐thermal power conversion and as transparent thermal insulators.This publication has 6 references indexed in Scilit:
