Abstract

Photoluminescence spectra of the ZnO carcass of inverted opal have been examined in the conditions of the strong light-to-structure interaction achieved by matching the photonic bandgaps of these photonic crystals to different parts of the ZnO emission spectrum. Developing the bands of enhanced spontaneous emission associated with both the emission of ZnO defects and the emission due to interband electron transitions has been observed. Interpretation has been given taking into account the coupling of emission to eigenmodes of 3-dimensional photonic crystal and the nature of the electron states involved in the radiative relaxation.
