Abstract

In this work, hybrid nanopillar forests (HNFs) are prepared based on a plasma repolymerization technique followed with a metal-nanoparticle deposition step. With these HNFs, an average absorptance as high as 84.1% in a wavelength range of 1.5-25 μm is achieved. The broadband high absorptance of the HNFs is regarded as a combined result from light trapping effect introduced by forests and surface plasmon resonance property induced by metal-nanoparticles. With such a broadband high absorptance, the HNFs are expected to be used as an effective absorber in infrared sensors thus to pursue higher performance, especially in devices like bolometers which are with small dimensions.
