“…VA-CNT arrays have the potential to provide order-of-magnitude improvement over current black paints and surface treatments and are considered as an interesting option for stray light control in optical space applications [5]. One of the challenges in space is the presence of cosmic radiation, especially for components directly facing to space.…”

This paper describes an experimental study of gamma radiation effects in low-density arrays of vertically aligned carbon nanotubes. These arrays are characterized by excellent anti-reflective and absorbing properties for wavelengths from UV to IR, which makes them an interesting option for stray light control in optical space applications. Gamma irradiation equivalent to an estimated surface lifetime exposition in geostationary orbit does not affect the reflectivity of the structures. First high-energy proton irradiation studies indicate that the reflectivity of the carbon nanotubes forests remains unchanged.

“…An ideal black body, which absorbs all electromagnetic waves at all wavelengths, plays an essential role in the development of modern physics and has numerous technological applications [1][2][3]. While an ideal black body is not achievable, a variety of material platforms have enabled ultrablack materials that have nearly zero reflection and emit radiation in accordance with the black body spectrum.…”

Abstract-Ultrablack materials play an essential role in astronomical observation and many thermal applications. Many material systems such as vertically aligned carbon nanotubes have produced extraordinarily high absorption, but require complicated fabrication. Here we report a single step self-masked etching process performed on compressed-coal graphite plates on a silicon substrate, which produces an ultrablack material with 0.7% hemispherical reflectance in the visible region and specular reflectance below 0.7% between 850 nm and 10 µm. Nanoscopic pieces of silicon are ripped off the substrate and deposit on the graphite resulting in carbon nanoneedle structures, which grow linearly with etching time reaching a height of 5.7 µm after 60 minutes.

“…These coatings were utilized as absorbers for large area pyroelectric detectors 54 and for reducing stray light in space borne instruments. 55,56 Antiresonant interference structures Antiresonance structures employ a quarter wave gap between a bottom reflector and the detector to couple a broadband signal into the absorbing bolometer. The bottom mirror is usually metallic.…”

A review is made of the physics and technology of spectrally selective thermal detectors, especially those operating at non-cryogenic temperatures. The background radiation noise fluctuations are rederived for arbitrary spectral characteristics. Infrared absorption due to phonons and free carriers is discussed followed by a review of published works on artificial infrared absorption materials such as patterned grids, nanoparticles, plasmonic structures, metamaterials and others. Subsequently, the literature of the spectral characteristics of broadband thermal detectors and spectrally selective thermal detectors is reviewed. Finally, the authors speculate on the directions that future research and development in the area will take regarding architectures, sensitivity and spectral characteristics.
