“…14a In addition, as black phosphorus is now readily available in gram quantities, 3 novel synthetic methods based on the direct modification of the bulk material might be feasible. Arc discharge methods used in synthesis of graphitic carbon nanostructures 31 and laser ablation techniques used to produce phosphorus clusters 32 are some examples of such methods, although the high-temperature nature of these techniques should be taken into consideration.…”

Structural and Electronic Trends among Group 15 Elemental Nanotubes

We have investigated the structural and electronic characteristics of single-walled nanotubes composed of group 15 elements P, As, Sb, and Bi. Systematic quantum chemical studies on the elemental nanostructures were performed to obtain periodic trends for their stabilities, structural principles, and electronic properties. By studying P, As, Sb, and Bi nanotubes up to 5.4, 5.0, 5.7, and 6.0 nm in diameter, respectively, we found their structures and stabilities to converge smoothly toward their experimental bulk counterparts. A rhombohedral structural model was found to be favored over an orthorhombic one for all the elements, but in accordance with the experimental characteristics of the elements also the orthorhombic model was found to be important for phosphorus. All studied group 15 nanotubes were found to be semiconducting.

“…Recently, we have successfully applied laser ablation (LA) and/or laser desorption/ionisation (LDI) to various systems, e.g. to the synthesis and identification of several new tellurium, sulfur, and tellurium‐sulfur clusters,11 phosphorus and phosphorus‐sulfur clusters,12 selenium sulfides,13 and arsenic and/or arsenic sulfide clusters,14 etc. Also, in order to enable analysis of aggressive compounds, we introduced the application of graphite microcrucibles as inert platforms for matrix‐assisted laser desorption/ionisation time‐of‐flight mass spectrometry (MALDI‐TOF‐MS),15 and demonstrated that MS analysis of highly aggressive compounds and/or liquids like concentrated sulfuric or selenic acid is possible 16…”

Laser desorption/ionisation and laser ablation of solid selenium trioxide, as well as the gas-phase behaviour of selenium trioxide, were studied. Selenium trioxide undergoes photochemical decomposition and, from the mass spectra obtained by laser desorption/ionisation time-of-flight mass spectrometry (LDI-TOF-MS), the following species were identified: O-, O2-, O3-, SeO-, SeO2-, SeO3-, SeO4-, Se2O7-, Se3O11-, and Se4O14-. Formation of the selenium superoxide SeO4- anion is described in this work for the first time. In addition, low-abundance selenium species such as Se2O8H2-, Se3O11H-, and Se4O15H2- were also detected. The stoichiometry of all ions was confirmed via isotopic pattern modeling and/or post-source decay (PSD) analysis. Photolysis of selenium trioxide leads partly to ozone formation. It was found that the most likely mechanisms of selenium superoxide formation are oxidation of selenium trioxide with ozone and/or reactive oxygen radicals, or photolysis of selenium trioxide tetramer (SeO3)4. Therefore, ab initio calculations were performed to support the mass spectrometric evidence and to suggest probable geometries for selenium superoxide anion SeO4- and diselenium superoxide anion Se2O7-, as well as to provide insight into and/or predict possible formation pathways. It has been found that both cyclic and non-cyclic peroxide structures of SeO4- and Se2O7- ions are possible. In addition, the SeO4 structure was also calculated guided by thermodynamic considerations using Gaussian-2 methodology, and the inferred stability of the SeO4 neutral molecule was supported by ab initio calculations.

“…Laser desorption ionization time‐of‐flight mass spectrometry (LDI‐TOFMS) is a powerful and useful technique to generate and study clusters formed during the laser ablation (LA) of solid materials. For example, the formation of phosphorus sulphides or selenides, arsenic sulphidesor selenides, sulphur tellurides, gold phosphides, gold tellurides, gold arsenides, and gold carbides, etc., has been studied. LA was also used for the analysis of various nano‐layers of solid materials, e.g.…”
