TL;DR: In this article, the electrodeposition of indium antimonide was investigated in a basic l-ethyl-3methylimidazolium chloride/tetrafluoroborate ionic liquid containing In(III) and sb(III).
Abstract: The electrodeposition of indium antimonide was investigated in a basic l-ethyl-3-methylimidazolium chloride/tetrafluoroborate ionic liquid containing In(III) and sb(III). Energy-dispersive spectroscopy data indicate that the composition of the In-Sb code-posits can be varied by deposition potential and concentration of In(III) and Sb(III) in the solution. At potentials where the deposition of antimony and indium is mass-transport limited, InSb compound can be obtained from solutions containing equal moles of Sb(III) and In(III). Analysis of the X-ray diffraction patterns indicates that the crystallinity of the electrodeposits is affected strongly by deposition temperature. The crystallinity of the deposits improves as the deposition temperature increases and crystalline InSb can be directly electrodeposited at 120°C. Photocurrent experiments indicate that the electrodeposited InSb was a p-type semiconductor. Infrared absorption measurements of the InSb deposits indicate a direct optical transition with an optical bandgap of 0.20 eV.

TL;DR: In this paper, a number of elements in the fourth, fifth and sixth group of the periodic system form hydrides upon reduction with sodium borohydride, which are stable enough to be of use for chemical analysis (Ge, Sn, Pb, As, Sb, Se, Te).
Abstract: A number of elements in the fourth, fifth and sixth group of the periodic system form hydrides upon reduction with sodium borohydride, which are stable enough to be of use for chemical analysis (Ge, Sn, Pb, As, Sb, Se, Te). Of these elements, we have investigated in detail arsenic, antimony, germanium and tin. The inorganic and organometallic hydrides are separated by a type of temperature-programmed gas-chromatography. In most cases it is optimal to combine the functions of the cold trap and the chromatographic column in one device. The hydrides are quantified by a variety of detection systems, which take into account the specific analytical chemical properties of the elements under investigation. For arsenic, excellent detection limits (≅40 pg) can be obtained with a quartz tube cuvette burner which is positioned in the beam of an atomic absorption spectrophotometer. For some of the methylarsines, similar sensitivity is available by an electron capture detector. The quartz-burner/AAS system has a detection limit of 90 pg for tin; for this element much lower limits (≅10 pg) are possible with a flame photometric detection system, which uses the extremely intense emission of the SnH molecule at 609.5 nm. The formation of GeO at the temperatures of the quartz tube furnace makes this device quite insensitive for the determination of germanium. Excellent detection limits (≅140 pg) can be reached for this element by the combination of the hydride generation system with a modified graphite furnace/AAS.
