Coordination compounds of indium. Part XXXIII. X-Ray photoelectron spectroscopy of neutral and anionic indium halide species

Abstract

. HABEEB, and DESAIS G. TUCK. Can, J. Chem. 55. 1527Chem. 55. (1977. The X-ray photoelectron spectra (metal and halogen energy levels) have been recorded for binary halides of indium in the +I; +II, and t I11 states, and for anionic halide corilplexes of indium (1) and (111). The results are internally consistent in terms of the relation between metal and ligand levels. but lattice effects prevent any detailed interpretation of indium levels in terms of oxidation state, ligand electronegativity, andjor coordination number.

Electrochemical Passivation of Homoepitaxial InP (100) Thin Films for Light Induced Hydrogen Evolution: A Synchrotron Radiation Photoelectron Spectroscopy Study

“…The emission at 5.1 eV, observed after the photoelectrochemical deposition of Rh, corresponds to the d-valence band structure of this metal (23). The SRPES spectrum, taken after the photoelectrochemical cycling in HCl solution (not shown) andthe electrodeposition of Rh (figure 6), shows a weak signal at 198.2 eV, which can be assigned to the Cl 2p signal of InCl (24).The Cl-signal after Rh deposition is stronger and more defined than that after cycling in HCl. This is consistent with the very weak In 3d 5/2 signal at 445.55 eV assigned to InCl 3 .…”

Photoelectrochemical Conditioning of MOVPE p-InP Films for Light-Induced Hydrogen Evolution: Chemical, Electronic and Optical Properties

“…The SRPES spectrum, taken after the photoelectrochemical cycling in HCl solution and photo electrodeposition of Rh, shows an emission line at 198.2 eV, which can be assigned to the Cl 2p signal of InCl 43 (see Fig. 9).…”

Improved electron collection in fullerene via caesium iodide or carbonate by means of annealing in inverted organic solar cells

“…It can be seen in Figure 6 that the doublet In3d corresponds to two doublets. The first one, with In3d5/2 = 444.5 ± 0.2 eV, corresponds to the indium bounded to oxygen in ITO, the second one, at In3d5/2 = 445.5 ± 0.2 eV, can be attributed to some indium bounded to iodine in the form InI 3 [15]. Moreover the ratio In ITO /In InI3 decreases significantly when the annealing temperature increases from 4 before annealing to 2 after annealing at 200…”

“…3). The binding energy of the iodine doublet is In3d5/2 = 618.2 eV and 619.1 when it is bounded as CsI [16] and InI 3 [15], respectively. As a matter of fact the iodine signal corresponds to two doublets the main one, situated at 618.8 eV, can be attributed to the indium compound.…”
