In oder to obtain the influence on the photonic localization in reverse opal photonic crystal constituted by TiO2, the photonic localization parameters are calculated numerically and analyzed theoretically, based on the Mie scattering theory and the low density approximation. It was found that the incidence wavelength and scattering body′ size have the obvious influence on localization phenomena in thesurplus ray zone of the oxide. The results show that the photonic localization phenomena appear in middle infrared band (13.3~15.3 μm) under the conditions of scatterer′s density of 10% and relative refractive index greater than 3.8. With the increase of the scattering body′s radius, the localization area shifts to long wavelength; simultaneously, the localization parameter firstly increases, then decreases. These research results can provide an academic reference to achieve experimentally the photonic localization phenomenon in the kind of photonic crystal.
