Abstract
Abstract
The work presents the results of the study of the photoluminescence spectra of the (111) growth surface of an opal - Bi12SiO20 matrix nanocomposite filled with europium (III) acetate hydrate (C6H9EuO6 × H2O). An increase in the integral luminescence intensity of the matrix composite opal - Bi12SiO20: Eu3+ compared to composite opal: Eu3+ was found. The measured photoluminescence spectra of the Bi3+ ions in the opal pores indicate its participation in optical processes as a co-activator of luminescence. A change in the character of the splitting of the main luminescence bands of Eu3+ ions in the region of 575–635 nm and the integral luminescence intensity after dehydration of the crystalline hydrate in opal pores has been established.
