Nano-Colors

In “nano-thin” layers Attophotonics creates a wide range of colors without the need for chemical pigments.

Due to their particular nanostructure the layers selectively reflect a specific spectral sub-fraction whereas other electromagnetic waves are absorbed efficiently. Thus, the surface shines, dependent on the viewing angle, in a well defined color. The same principle gives rise to the sparkling colors of the wings of some butterflies.

Key properties of Attophotonics’ nano-colors scale_butterfly

  • A wide spectrum of colors
  • can be printed or applied directly
  • onto arbitrary surfaces
  • with the same chemistry (several options available)
  • efficiently using materials.
  • The coatings create a modern, metallic look
  • are color-fast,
  • extremely heat stable (600°C) if required and
  • machine-readable.
  • They show characteristic absorption in the visible as well as in the IR- and UV-light spectrum.
  • They can be used for colored bar-codes and
  • anti-counterfeiting tags.
  • Glitter-effects and
  • color gradients can also be created.

The potential applications of this innovative new technology range from novel surface design and POC-diagnostics to intelligent packaging for quality control of food products.

Forms of application

Depending on material, desired additional properties and required resistance to mechanical stress, Attophotonics’ nano-colors can be applied in various ways:

  • direct coating
  • glitter
  • films, stickers/ tags
