Directional emission of colour-converted light-emitting diodes (LEDs) can be enhanced and accurately controlled using hexagonal arrays of aluminum nanoparticles, which sustain plasmonic-photonic modes. Left: scanning electron micrograph of a nanoimprinted hexagonal array with a lattice constant of 375 nm. Right: Fourier image of the directional emission of a light-emitting device featuring such an array.
