“…This magnitude is consistent with increase of the sample weight after ZnO infiltration [17,20,21,23]. However, it should be noted that the filling factor can be very high and increased up to $90% in the inverted opals [14].…”

“…Preliminary studies concerning optical properties of ZnO nanocrystals inside the synthetic opal obtained by using the spray pyrolysis method have been reported [17][18][19][20][21][22][23]. Despite the high density of crystal defects, a strongly dominant UV-blue emission in the PL spectra of polycrystalline ZnO was observed.…”

The effect of bound optical modes of photonic glasses from silica spheres on their luminescence in the visible range of the spectrum is investigated. It is shown that local photonic states give rise to a fine structure in luminescence spectra, positions of the maxima of which depend on the diameters of SiO 2 nano spheres. A theoretical model of the calculation of characteristic wavelengths of bound modes and values of the Purcell factor for the amplification of spontaneous luminescence into these modes is proposed. It is revealed that the experimental data agree well with theoretical results for the intrinsic luminescence of pho tonic glasses with different diameters of silica spheres.

“…A three-dimensional (3D) periodic array of ZnO can also be assembled, by means of chemical deposition in a solution containing a zinc-nitrate precursor followed by thermal annealing [26][27][28][29][30]. The first investigations of 3D periodic arrays of ZnO showed that artificial opal could be used to modify effectively the PL emission for the infiltrated ZnO nanoparticles [26,27].…”
