Abstract

The structure of the opal-ZnO composites has been studied by TEM and X-ray methods. It was found that the solid state reaction of the opal-ZnO interface interaction is occurring during the heat treatment of the infiltrated samples resulting in the formation of the zinc silicate β-Zn₂SiO₄ and its high temperature modification of willemite Zn₂SiO₄. Nanocomposite structure and emission properties have been studied in dependence on the filling degree. The blue luminescence at 430 nm stipulated for the β-Zn₂SiO₄ phase has been observed for the sample with 25 filling cycles. Angular dependences of the PL and Reflection spectra of the opal-ZnO composite with 4 filling cycles demonstrate the suppression effect of the ZnO spontaneous emission in the stop band.
