Synthesis of alpha-tellurium dioxide nanorods from elemental tellurium by laser ablation
- 化学化工－已发表论文 
Elemental tellurium was evaporated by laser ablation, the vapor of which was condensed and deposited on the surface of the heated glass surface and then formed alpha-tellurium dioxide nanorods with uniformly size distribution by oxidation in the chamber with hot air atmosphere. TEM images and Electron diffraction (ED) pattern confirm the crystallinity of alpha-phase tellurium dioxide. The formation process of the nanorods involves a vapor-liquid-solid (VLS) following a chemical oxidation in the hot air atmosphere, in which the low melting point tellurium serves as a liquid-forming reagent.
