Characterization of Te nanoparticles synthesized by plasma processing

Publication date: Available online 17 May 2019Source: Radiation Physics and ChemistryAuthor(s): Fabio Iesari, Keisuke Hatada, Jigar Patel, Chidambara Balasubramanian, Takafumi Miyanaga, Hiroyuki IkemotoAbstractThe local structure of Tellurium nanoparticles synthesized by arc plasma were studied by X-ray absorption spectroscopy. Nanoparticles were characterized by using different techniques to reveal particles size, morphology and composition. Te K-edge EXAFS spectra reveal a structure similar to trigonal Te, where both the inter-chain and intra-chain bonds, typical of Te crystal structure, are present. Evolution of the Debye-Waller factor with temperature reveals an increased static disorder in the nanoparticles respect to the trigonal material.
