Analysis of stop zones of photonic-crystalline structures of anodic aluminum oxide

The influence of the temperature and composition of the electrolyte, the number and value of the periods of photonic crystal (PC) structures of anodic oxide on aluminum and without aluminum on the spectral position of the stop zones (SZ) was studied. A hypsochromic shift of the SZ maximum by 76 nm was established with an increase in the electrolyte temperature from 7 to 12$^\circ$ C and by 103 nm with a change in the number of periods from 52 to 230, a bathochromic shift by 160 nm with an increase in the structure period by 1.5 times. PC structures with a transmittance of 0.1% and a reflectivity of 83% in the SZ region were obtained. The PC structures have a color, the colorimetric characteristics are determined, presented on the chroma ticity diagram and are consistent with the SZ position.
