This paper presents the results of experimental studies for the luminescence spectral intensity redistribution of opal photonic crystals containing various active dielectrics - Bi12SiO20, opal - Bi2TeO5 and opal - NaBi(MoO4)2 matrix nanocomposites and filled with europium C6H9EuO6 x H2O salt. Ultraviolet excitation was provided by semiconductor laser operating at wavelengths of 400nm and 100 mW average power. An increase in the integral luminescence intensity of the matrix composite opal - Bi12SiO20: Eu3+ was found. The possibility of the participation of bismuth ions as a co-activator and luminescence concentrator also is analyzed. It has been proposed to use opal-Bi12SiO20 nanocomposite filled with europium as a potentially attractive material to improving the solar cell efficiency.
