Аннотация
The colloidal solutions and deposited layers of FemOn–SiO2 composite particles were studied. The colloidal solutions were prepared by precipitation of FemOn on the surface of porous silicon dioxide particles synthesized from a tetraethoxysilane (TEOS) alcohol solution by the sol‒gel method. It was found that, in the visible and near-UV ranges of the absorption spectra, there are six bands typical of conglomerates of FemOn nanoparticles. The investigation of Raman spectra of the samples subjected to laser annealing and γ-irradiation revealed the phase transitions Fe3O4 → γ-Fe2O3 → α-Fe2O3.
