The team’s ultrablack coating can be applied to curved surfaces and magnesium alloys to trap nearly all light. Credit: Jin et al.Sometimes, seeing clearly requires complete black. For astronomy and precision optics, coating devices in black paint can cut down on stray light, enhancing images and boosting performance. For the most advanced telescopes and optical systems, every little bit matters, so their manufacturers seek out the blackest blacks to coat them.
“One big advantage of the ALD method lies in its excellent step-coverage ability, which means we can obtain uniform film coverage on very complex surfaces, such as cylinders, pillars, and trenches,” said Cao. “TiAlC acted as an absorbing layer, and SiO2 was employed to create an anti-reflection structure,” said Cao. “As a result, nearly all of the incident light is trapped in the multilayer film, achieving efficient light absorption.”In tests, the team found an average absorption of 99.3% across a wide range of light wavelengths, from violet light at 400 nanometers all the way to near-infrared at 1,000 nanometers.

Blueberries get their blue color from tiny structures in their wax coatingResearchers at the University of Bristol have discovered that the blue color of blueberries is not due to pigments in the fruit skin, but rather from tiny structures in their wax coating. This finding opens up possibilities for sustainable and biocompatible colorants and coatings inspired by nature.
