Abstract

Pulsed laser ablation (PLA) in liquid is advanced method for obtaining active nanoparticles in pure solvents without the use of chemical precursors. In this work, an original approach to the synthesis of complex oxides of bismuth and silicon (BSO) is proposed. The initial colloids obtained by PLA (Nd:YAG laser, 1064 nm, 7 ns) of Bi and Si targets in water were mixed and subjected to additional irradiation with the same laser parameters. Laser treatment stimulated the formation of complex oxides. Then the colloids were dried in air and nanopowders obtained were studied by X-ray diffraction (XRD), transmission electron microscopy (TEM) and UV-Vis spectroscopy. The photocatalytic activity of the materials was examined in the Rhodamine B degradation under LED source irradiation (375 nm).
