One of the most intriguing problems light transport in solids is localization that has been observed various disordered photonic structures1-11. The defect-free icosahedral quasicrystals recently predicted theoretically without experimental verification10. Here we report on fabrication submicron-size dielectric and demonstrate results detailed studies properties these structures. Here, present first direct observation intrinsic quasicrystals. This result was obtained time-resolved measurements at different laser wavelengths visible. We linked with aperiodicity structure, which led to uncompensated scattering from an individual structural element over entire sphere, providing multiple inside sample and, as a result, light.
