- Аннотация: In this work, silicon and iron composite is synthesized by femto-second laser ablation of the target, consisting of a mixture of silicon and α‑iron silicide in acetone. Scanning electron microscopy shows that the composite consists of spherical nanoparticles with a diameter ranging from 20–250 nm with a logarithmic normal distribution. According to the X‑ray diffraction analysis, the composite is not well crystallized and contains some silicon. Raman spectroscopy confirms the presence of crystalline silicon in the composite. The synthesized composite possesses low transmittance in the range from 350–1000 nm not exceeding 30%. The photothermal characterization is conducted using 830 nm continuous wavelength laser. Prior to the characterization, the surface of silicon and iron composite is modified with pluronic F‑127 with its subsequent transfer from acetone to water. The photothermal characterization shows a high photon conversion efficiency (~17.0%) and excellent photostability of the composite. This composite can probably be used as a nanomaterial for the photothermal treatment of cancer.
