X-ray photoemission studies of tellurium and some of its compounds

Abstract

The energies of the 3p1/2,3/2, 3d3/5,5/2, 4s, and 4d3/2,5/2 photopeaks have been measured for tellurium metal and 23 of its compounds. An attempt is made to interpret chemical bonding in some of the tellurium compounds by comparing core level binding energy shifts with isomer shifts observed through Mossbauer spectroscopy. The widths of the 3p3/2 photopeaks measured relative to the 3p1/2 photopeaks are examined for broadening by electric field gradients and Coster–Kronig transitions. Variations in the spin–orbit splitting of the tellurium 4d level in its various compounds do not seem to be dependent on crystal field interactions.

Analysis of Te and TeO<sub>2</sub> on CdZnTe Nuclear Detectors Treated with Hydrogen Bromide and Ammonium-Based Solutions

“…The binding energies for the TeO 2 species for the 3d 3/2 and 3d 5/2 doublets are approximately 586.5 eV and 576.1 eV respectively [22]. These binding energies were reported by Bahl et al [22] with and estimated error of ±0.2 eV, and by Egarievwe et al [11] with an estimated error of ±0.4 eV. We can see from Figure 2that TeO 2 species were formed during the surface passivation stage.…”

“…The binding energies for the Te elemental states appear for the 3d 3/2 and 3d 5/2 doublets at approximately 583.5 eV and 573.1 eV respectively [22]. The binding energies for the TeO 2 species for the 3d 3/2 and 3d 5/2 doublets are approximately 586.5 eV and 576.1 eV respectively [22].…”

Room-Temperature Chemical Synthesis of Silver Telluride Nanowires

“…The XPS data are similar to those reported previously. 29,30 The quantification of peaks indicates a stoichiometry ratio of Ag to Te of 2:1.…”

Synergetic effect of Te2MoO7 and MoO3 (WO3) oxides in the partial oxidation of propylene

“…Table 1 gives the results of the XPS analysis obtained for some of the catalysts before and after the catalytic test. As reported in the literature [10,11], the valence state of Mo and Te was determined to be ?6 and ?4, respectively. After reaction, the binding energy of Mo 3d 5/2 and Te 3d 5/2 changed little, indicating the oxidation degrees of molybdenum and tellurium are not modified by the catalytic test.…”
