Morphology of Tungsten Nanooxides, Synthesized by Laser Ablation of Metal in Water
- 19 Downloads
Colloidal solution precipitates obtained during laser ablation of tungsten in water and containing nanostructured metal oxides are studied using X-ray diffraction and scanning electron microscopy. The nanostructure composition and morphology are analyzed. It is shown that the material composing nanostructures is X-ray amorphous, i.e., the particle size does not exceed 1–2 nm. The high degree of the structure surface development implies prospects of their use as substrata when analyzing the composition of various materials by surface-enhanced Raman scattering.
