FIELD: physics; optics.
SUBSTANCE: invention relates to the technology of optoelectronic devices and can be used for making luminescent photonic crystalline information display devices with controlled radiation directivity. The method of making luminescent photonic crystals with controlled radiation directivity involves using a photonic crystal matrix in form of an ordered structure based on monodispersed polystyrene microspheres which are hardened at 100°C. The luminescent substance used is layers of organic complexes of rare-earth elements HEuEDTA, Tb("руса")3 with less than 20 nm of the half-width emission line, not subject to concentration quenching.
EFFECT: obtaining luminescent photonic crystals with controlled radiation directivity, suitable for making optoelectronic devices with directed radiation at wavelengths λ=620 and 580 nm in an interval of angles of 0-30°.
