Resonance Globular Photonic Crystals Filled with Al2O3:(Cr3+) Nanoparticles

A problem of theoretical and experimental research of resonance globular photonic crystals is solved by example of opal matrices filled with Al2O3:(Cr3+) nanoparticles. The artificial opals with different-diameter globules (200, 290, and 340 nm) at fixed concentration of chromium ions were objects for investigations. The presence of chromium ions led to a resonance of the nanocomposite medium permittivity at a wavelength of 694.3 nm. It is found that a position of the resonance dispersion branch in the crystal under study changes depending on a diameter of the globules. In particular, the resonant level is in the bandgap of the nanocomposite photonic crystal at a globule diameter of290 nm.
