Abstract

Visually transparent, but infrared reflecting and electrically conductive coatings are usually made of highly doped tin oxide or indium-tin oxide /1/. However, multilayer structures using induced transmission of a thin metal film /2/ offer several advantages compared to the single layer oxide coatings. For applications as optically transparent heat mirrors or electrically conductive electrodes relatively thin layers are required. This results in faster deposition cycles, lower material cost, less variation in interference colours and less severe step coverage problems. For coatings incorporating a metal film a higher NIR reflectivity can be achieved as well. In this study we report on optical and electrical properties of TiO₂/Ag/TiO₂ multilayer coatings.
