A thin film, which reflects infra -red ray while transmits visible light, is discussed in a background of energy saving incandescent lamps.The film which consists of multi -layer TiO2 -SiO2 film reflects infra -red ray effectively and has a high heat resistance. This film is formed from organometallic solutions by dipping method.In order to carry out multi -layer coatings, the organometallic solutions are improved. A film on a substrate turns into a metalic oxide film having desired optical thickness and refractive index. The optical properties of this film and its application to tubular tungsten halogen lamps are discussed in this paper.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
