Project Member(s): Smith, G., Cortie, M., Arnold, M.

Funding or Partner Organisation: Australian Research Council (ARC Discovery Projects)

Start year: 2014

Summary: The aim of this project is to generate a complete scientific understanding of a new generation of hybrid, tri-layered, optically-selective coatings. The new design paradigm combines the very different attributes of smooth and nanostructured layers so that superior and simultaneous control of both spectral and angular properties of light can be achieved. Existing theory will be extended so that quantitative analyses of these new systems and other hybrids become possible and new and improved fabrication techniques will be developed. The work will unlock new technological possibilities for coating performance and application and is likely to be associated with significant improvements in energy conservation and generation.
