Self-assembled nanostructured multilayered spectral filters

Multilayered optical filters have been formed using layer-by-layer self-assembly processes. Unlike conventional vapor deposition coating techniques, molecular-level self-assembly is an aqueous solution-based process that is performed at room temperature and pressure. This allows the incorporation of a wider range of possible materials, including polymers, oxide and other nanoclusters, and other molecules. We review the general filter deposition method and give generalized results for nominal substrate materials.
