Abstract
The templating method based on sol-gel technology for creation hybrid silicate materials with effective luminescence was described. The lyotropic liquid-crystalline (LC) system containing Eu^III ions – C₁₂H₂₅O(CH₂CH₂O)₁₀H/Eu(NO₃)₃·6H₂O/H₂O was used as a template. Conditions of the synthesis were established. The role of the liquid-crystalline template was shown. Evaluation of the changes of the surface topography of the film during the transition to the LC template in comparison to simple silicate matrix was carried out. The influence of composition on the luminescence properties of hybrid films was investigated.

Keywords: lyotropic liquid crystal, sol-gel technology, lanthanide, luminescence
