TL;DR: In this paper, the ultrathin peroxoantimonate coating of graphene oxide from hydrogen peroxide-rich solutions of hydroxoantimony was demonstrated and an amorphous 1-2 nm Sb (V) oxide film was formed and can be further crystallized by exposure to an electron beam to give a 2-5nm thick supported Sb 6 O 13 particulate coating.

TL;DR: In this paper, the effect of antimony surfactant on the growth of InGaAs multiple-quantum-well (MQW) structure by metalorganic vapor phase epitaxy and the application of the structure to buried-heterostructure (BH) lasers was reported.
Abstract: We report on the effect of antimony surfactant on the growth of strained InGaAs multiple-quantum-well (MQW) structure by metalorganic vapor phase epitaxy and the application of the structure to buried-heterostructure (BH) lasers. For a 1.85%-strained MQW, supplying a small amount of antimony during well growth is effective in suppressing the three-dimensional growth and increasing the photoluminescence peak intensity at a wavelength of 2.09 μ m . The secondary ion mass spectroscopy measurement reveals that hardly any antimony is incorporated into the wells. The fabricated BH laser has an emission wavelength of 2.103 μ m under continuous-wave operation at 25 °C.

TL;DR: In this article, a new chemical deposition method was developed to prepare photoconducting n-Sb 2 S 3 thin polycrystalline films, and the solution composition of the deposition bath was 0.025M potassium antimonyl tartarate, 0.4M triethanolamine, and 5×10 -7 M silicotungstic acid (STA), respectively.
Abstract: A new chemical deposition method has been developed to prepare photoconducting n-Sb 2 S 3 thin polycrystalline films. The solution composition of the deposition bath was 0.025M potassium antimonyl tartarate, 0.4M triethanolamine, 0.025M thioacetamide, and 5×10 -7 M silicotungstic acid (STA), respectively. The as-deposited and the annealed films were characterized through x-ray diffraction, neutron activation analysis, and the optical absorption investigations. The photoelectrochemical performances of these films were examined

TL;DR: In phase: The title compounds lie in a new region of phase space for such a structure, and have stoichiometries in accord with a classical Zintl phase formulation as mentioned in this paper.
Abstract: In phase: The title compounds lie in a new region of phase space for such a structure, and have stoichiometries in accord with a classical Zintl phase formulation. The small semiconductor gaps indicated by DFT calculations are also supported by their diamagnetic susceptibilities.

TL;DR: Euhedral macrocrystals of Pt-Fe alloy from the Kondyor PGE placer, Khabarovskiy Kray, eastern Siberia, Russia, have a relatively constant composition of Pt2.4-2.6Fe, tin and antimony contents up to 0.3 wt.%, and an unusually low content of all PGE except Pt. The macrocystals have a complex gold-rich rim, with four groups of gold alloy: tetra-auricupride (the most abundant gold-bearing phase), Au-Ag
Abstract: Euhedral macrocrystals of Pt–Fe alloy from the Kondyor PGE placer, Khabarovskiy Kray, eastern Siberia, Russia, have a relatively constant composition of Pt2.4–2.6Fe, tin and antimony contents up to 0.3 wt.%, and an unusually low content of all PGE except Pt. The millimetric crystals contain inclusions of fluorapatite, titanite, phlogopite, magnetite, ilmenite and iron–copper sulfides. The macrocrystals have a complex gold-rich rim, with four groups of gold alloy: tetra-auricupride (the most abundant gold-bearing phase), Au–Ag (98–54 wt.% Au), Au–Ag–Cu–Pd and Au–Pd–Cu alloys. The inner part of the reaction rim hosts a variety of PGE minerals, such as stannides, antimonides and tellurobismuthides of Pd and Pt. Stannides occur as copper-bearing (taimyrite–tatyanaite series) and copper-free compounds (atokite–rustenburgite series). The main antimony mineral is Sn-bearing mertieite-II. Tellurobismuthides are represented by Te-rich sobolevskite and an intermediate member of the moncheite–insizwaite solid-solution series. The reaction rim also hosts several unknown phases, such as Pd7Bi3, Pd3Bi, Bi2O3•3H2O, and a phosphocarbonate of thorium. The coarse crystals occur in eluvial and alluvial placers within the Kondyor massif, a zoned clinopyroxenite–dunite intrusion of Paleozoic or Mesozoic age. The inclusion assemblage suggests that the macrocrystals of Pt– Fe alloy are associated with late apatite – magnetite – phlogopite clinopyroxenite bodies, and possibly formed in a late–magmatic pegmatitic environment. The Pt–Fe alloy crystals have undergone hydrothermal overprint by NaCl-rich solutions bearing gold – silver – palladium – copper, which produced a wide variety of intermetallic compounds as well as Pd-bearing intermetallic phases. The aqueous solutions also had a minor but characteristic bismuth – tin – antimony – tellurium component.
