One of the most intriguing problems of light transport in solids is the localization that has been observed in various disordered photonic structures. The light localization in defect‐free icosahedral quasicrystals has recently been predicted theoretically without experimental verification. Herein, the fabrication of submicron‐size dielectric icosahedral quasicrystals is reported and the results of detailed studies of the photonic properties of these structures are demonstrated. The first direct experimental observation of intrinsic light localization in defect‐free quasicrystals is presented. This result is obtained in time‐resolved measurements at different laser wavelengths in the visible. The localization is linked with the aperiodicity of the icosahedral structure, which leads to uncompensated scattering of light from an individual structural element over the entire sphere, providing multiple scattering inside the sample and, as a result, the intrinsic localization of light.

光子二十面体准晶体中本征光定位的实验观察

固体中光传输最令人着迷的问题之一是在各种无序光子结构中已观察到的局部化。从理论上讲，无缺陷的二十面体准晶体中的光定位是未经实验验证的。本文报道了亚微米级介电二十面体准晶体的制备，并证明了对这些结构的光子特性进行详细研究的结果。提出了对无缺陷准晶体中本征光定位的首次直接实验观察。该结果是在可见光中不同激光波长的时间分辨测量中获得的。定位与二十面体结构的非周期性相关，
