Outline of Final Research Achievements

Regarding the research on photothermal conversion with nanoparticles, we demonstrate that titanium nitride nanoparticles are efficient sunlight absorbers and solar heat generators. When titanium nitride nanoparticles are dispersed in water, the heating and evaporation rates increase significantly.
With regard to the work on infrared absorption and emission, we demonstrate that even one dimensional structure can achieve wavelength selective narrowband thermal emission. The excitation of Tamm surface plasmon is the key which can be excited at the metallic thin film and distributed Bragg reflector made of dielectrics.
