摘要

我们展示了在难熔等离子体材料(钨)上使用随机结构的宽带光谱吸收器，在200 nm至1100 nm波长范围内吸收效率超过90%。在相同参数下的数值模拟结果与实验结果吻合较好。随机纳米结构比周期性纳米结构提供了更多的自由，增强了吸收和光谱选择性。

Absorption enhancement and spectrum selectivity of refractory plasmonic nanostructures

We demonstrate a broadband spectrum absorber using random structures on refractory plasmonic material (Tungsten) resulting in the absorption efficiency over 90% in the wavelength range from 200 nm to 1100 nm. Numerical simulations for the structure with same parameters agree well with the experimental results. Random nanostructures provide more freedom for enhancing absorption and spectrum selectivity than periodic nanostructures.
