A thermal barrier coating has several different layers, the first of which is an oxidation barrier. A phonon scattering zone is positioned on top of the oxidation barrier. The phonon scattering zone includes a plurality of phonon scattering interface layers, each of which is formed between a first ceramic material and a second ceramic material. The first and second ceramic materials are each between 1 and 1000 nanometers thick. An optical reflectance zone is positioned on the phonon scattering zone. The optical reflectance zone includes a second stack of ceramic materials with a plurality of optically reflecting interface layers, each of which is formed between a first ceramic material and a second ceramic material. The first and second ceramic materials are each between 0.1 and 1.0 microns thick.
