  • Tunable infrared reflectance by phonon modulation
    Patent number: 9909233
    Abstract: The present invention pertains to the use of mobile coherent interfaces in a ferroelectric material to interact with optical phonons and, ultimately, to affect the material's optical properties. In altering the optical phonon properties, the optical properties of the ferroelectric material in the spectral range near-to the phonon mode frequency can dramatically change. This can result in a facile means to change to the optical response of the ferroelectric material in the infrared.

  • METHOD OF FORMING A THERMAL BARRIER COATING
    Publication number: 20170279024
    Abstract: A method of forming a thermal barrier coating is disclosed. The method may include providing a solution containing strontium and niobium and applying the solution to a substrate via a chemical solution deposition process to form a first film layer on the substrate. The method may further include pyrolyzing the first film layer and annealing the first film in an air atmosphere to form a strontium niobate coating.
