| Outline of Final Research Achievements |
In this research, we try to realize high-performance spectrally selective emitter at high-temperature by suppressing emission property in infrared range. Main achievements are shown in followings.
(1) Systematization of fundamental knowledges on the device controlling thermal radiation spectrum with considering oxidization of refractory metals. (2) Understanding of degradation mechanism on spectrally selective property of Ni based superalloys. (3) Detail analysis on high spectrally selective emission properties of metal-dielectric multilayer structure based on the knowledge from Ni-based superalloys, and evaluation of the fabricated multilayer structures. (4) Demonstration of high-temperature stability of the multilayer structures.
