A B S T R A C TRegular sized nanostructures of indium oxide (In 2 O 3 ) were homogeneously grown using a facile route, i.e. a microwave-hydrothermal method combined with rapid thermal treatment in a microwave oven. The presence of Er 3+ doping plays an important role in controlling the formation of cubic (bcc) and rhombohedral (rh) In 2 O 3 phases. The samples presented broad photoluminescent emission bands in the green-orange region, which were attributed to the recombination of electrons at oxygen vacancies. The photocatalytic activities of pure bcc-In 2 O 3 and a bcc-rh-In 2 O 3 mixture towards the UVA degradation of methylene blue (MB) were also evaluated. The results showed that Er +3 doped In 2 O 3 exhibited the highest photocatalytic activity with a photonic efficiency three times higher than the pure oxide. The improved performance was attributed to the higher surface area, the greater concentration of electron traps due the presence of the dopant and the possible formation of heterojunctions between the cubic and rhombohedral phases.

“…The investigation of optical properties for new luminescent materials on the basis of synthetic opals which represent a class of 3D photonic crystals and offer a potentially opportunities to investigate the effect of spontaneous emission, low-threshold lasing, information processing and transferring (Joannopoulos, Villeneuve, & Fan, 1997). In (Aliev et al, 2002;Li et al, 2007;Gorelik, Lepnev, & Litvinova, 2017) it is shown that erbium (Er 3+ ), europium (Eu 3+ ) and terbium (Tb 3+ ) are perspective materials for filling opal pores. Special interest from the scientific and practical points of view represents nanocomposites opal-active dielectric, which activated by luminescent centres.…”

This paper presents the results of experimental studies for the luminescence spectral intensity redistribution of opal photonic crystals containing various active dielectrics -Bi 12 SiO 20 , opal -Bi 2 TeO 5 and opal -NaBi(MoO 4 ) 2 matrix nanocomposites and filled with europium C 6 H 9 EuO 6 x H 2 O salt. Ultraviolet excitation was provided by semiconductor laser operating at wavelengths of 400nm and 100 mW average power. An increase in the integral luminescence intensity of the matrix composite opal -Bi 12 SiO 20 : Eu 3+ was found. The possibility of the participation of bismuth ions as a co-activator and luminescence concentrator also is analyzed. It has been proposed to use opal-Bi 12 SiO 20 nanocomposite filled with europium as a potentially attractive material to improving the solar cell efficiency.

Quantum Optics and Laser Experiments 88 allows modifying optical properties of such systems by filling the pores with various substances. Synthetic opal photonic crystals containing nonlinear optical substances give a good chance to observe quantum optics phenomena in spatially nonuniform media where the photon mean free path is close to the light wavelength. Moreover, in this case the input optical power that is necessary to observe phenomena may be lower than the power required usually for observing the same phenomena in uniform nonlinear substances. The reason for it is the existence of diffuse transfer of photons that can result in photon accumulating inside photonic crystals and, consequently, in local optical power increasing. In particular, the possibility of experimental manifestation of Raman scattering and spontaneous parametric down-conversion in synthetic opals is discussed (Gorelik, 2007). The latter phenomenon is of special interest as it is convenient method to obtain bi-photon fields consisting of correlated photon pairs (Kitaeva & Penin, 2005). In the recent years, crystals with chirped structure of quadratic susceptibility (Kitaeva & Penin, 2004), and materials with spatially regular and stochastic distribution of quadratic optical susceptibility (Kalashnikov et al., 2009), are considered as sources of bi-photons. It is quite possible synthetic opal photonic crystals will be ranked with these sources.
