The composites opal–Zn2SiO4:Mn and opal–GaN–ZnS:Mn were synthesized by chemical bath deposition. These materials are perfect three-dimensional photonic crystals which produce effective fluorescence at room temperature when excited by an alternating current electric field. The electroluminescence spectrum is considerably modified by the photonic band gap to become anisotropic in accordance with the photonic band gap angular dispersion.
