Nanoscale multilayer coatings with alternating layered structures (<100 nm) have been used to synthesize materials with extraordinary mechanical properties. Optical nanomultilayers are composed of layer materials with desirable optical properties, and the layer thicknesses determine light propagation through the material. The interplay of nanolayers increases the potential for multifunctionality, such as maximizing both optical and mechanical performance.
In this work, ceramic/ceramic systems were synthesized using DC/RF reactive magnetron sputtering and configurations were designed using predictive calculations to maximize transmittance. Microstructural characterization including TEM and STEM were used to analyze the effect of layer thickness on microstructure and layer interfaces, as well as optical performance from spectrophotometry and ellipsometry measurements. Nanoindentation was performed to analyze hardness and elastic modulus as a function of optical performance. By combining these techniques, the behavior of optical multilayers was explored for the development and synthesis of optical multilayers with high optical and mechanical performance.
