Temperature dependent ellipsometry results reveal the pronounced reflection near the IRspectrum above the transition and an almost temperature independent weak reflection in the visible spectrum. Theinfrared reflection displays a strong hysteresis during heating and cooling near the transition temperature at 68°C,indicating a first order transition and a strain-free structure. Our work demonstrates the feasibility to obtain high qualityphase change nanostructures that transmit the visible spectrum but reflect infrared and is suitable for large scalefabrication.
