Abstract

r-BS was synthesized under high pressure/temperature conditions. Rietveld analysis of the powder X-ray diffraction data was performed by applying the structure model of GaS 3R (space group: R3m) with the lattice parameters of ahex = 3.05223(7) Åand ahex = 20.4119(5) ÅThe crystal structure of r-BS was revealed to be the three-layer structure comprised of the units built up from B-B pairs which are inside the anti-prism of S atoms. The measurement of UV-Vis diffused reflectance spectrum showed that the estimated band gap of r-BS was about 3.4 eV, and the coloring of r-BS was observed as broad absorption at 510 nm.
