The absorber is attached to a photonic crystal composed of a stack of silicon and silicon dioxide layers that begins to glow at such high temperatures.

«It is particularly refreshing to see simple techniques such as inkjet printing being used to such great effect,» says Thomas Krauss who investigates photonic crystals at the University of York.

Inkjet printing of photonic crystals onto a surface is cheaper, but previous efforts have struggled to integrate responsive photonic crystal inks into such a system.

For example, photonic crystals could funnel excess heat from a power plant's generator and release it over a much smaller band of frequencies to drive engines — such as those in electric - powered cars that can absorb energy only within a small range — much more efficiently.

In packed, two - dimensional crystalline systems, such as in photonic two - dimensional crystals, the particles are organized in hexagonal lattices.

Such omnidirectional reflectance for dielectric structures is associated with three - dimensional photonic crystal nanostructures that sustain a so - called complete photonic band gap.
