Kelm, S. Korovin, V. Pustovoy, A. Surkov, A. Vladimirov] Silicon nanoparticles (nSi) with unusual properties were studied. After suggested treatment they became luminescent and also acquired a magnetic moment. Nanoparticles were prepared by laser pyrolysis of silane in a gas flow reactor followed by chemical treatment in methanol (MeOH) + HF + FeCl3 solution. After the treatment. nanoparticles gained stable luminescence with the peak position dependence on the excitation wavelength. With increasing of the excitation wavelength from 365 to 456nm, the photoluminescent peak shifted from 632 to 665nm. Luminescence of such nanoparticles had blue shift in comparison with the nanoparticles etched in widely-used solution for the silicon—MeOH + HF + HNO3. Moreover, after such treatment the magnetic moment of nanoparticles appeared, which is not inherent for the as-prepared nSi. Multifunctional silicon nanoparticles with both stable luminescence and magnetic moment at the same time are perspective for biology and medicine use as the optical and magnetic markers.
