- Аннотация: A procedure for the chemical immobilization of a new Zn II –Eu III heterobimetallic complex in the SiO 2 aerogel matrix has been developed. In this Zn–Eu complex, a peripheral non-luminescent Zn ion acts as a binder to a silica matrix and prevents direct interaction of rare-earth ions with OH− and NH− groups in the silica matrix, which would have a detrimental effect on the luminescence of lanthanides. The procedure includes the synthesis of complexes, co-gelation of the obtained complex with SiO 2 sol, the washing of lyogels, and their subsequent supercritical drying in CO 2 . The composition and properties of the obtained aerogels were investigated using a low-temperature nitrogen adsorption technique, helium pycnometry, FTIR, Raman, UV–visible, and luminescence spectroscopy, XPS, PXRD, SEM, TEM, TGA combined with mass spectrometry, and small-angle neutron scattering. The aerogels modified with the Zn II –Eu III complex demonstrated strong red luminescence upon excitation with UV light.
