设计、制作了一种高温稳定宽带等离子体吸收体，并对其进行了光学表征。采用难熔等离子体材料氮化钛制备了平均高吸收率为95%、总厚度为240 nm的宽带吸收体。这种吸收体既能吸收等离子共振又能吸收介电损耗。它为太阳能热光电和光学电路等有趣的应用开辟了一条道路。
A high-temperature stable broadband plasmonic absorber is designed, fabricated, and optically characterized. A broadband absorber with an average high absorption of 95% and a total thickness of 240 nm is fabricated, using a refractory plasmonic material, titanium nitride. This absorber integrates both the plasmonic resonances and the dielectric-like loss. It opens a path for the interesting applications such as solar thermophotovoltaics and optical circuits.
