Title : Recent advances in unusual optical coatings for flexible device application

Abstract:

Optical coatings on the basis of thin-film interference have been widely used as key elements in various optical components and optoelectronic devices. For example, anti-reflection or high-reflection is observed under conditions of constructive or destructive interference achieved by multi-layer stacks of dielectric materials. On the other hand, unusual optical coatings in terms of their geometry and functions have recently been studied for new type of optical devices. In this presentation, we show three different types of optical coatings, i.e., 1) ultra-thin films with highly absorbent media for coloration, 2) flexible and transparent electrodes based on epoxy-copper-ITO, and 3) colored, daytime radiative cooling structures for aesthetic purpose.
