WebIn this work, we present a solvothermal method to prepare bismuth (Bi)-doped CuGaS 2 chalcopyrite nanocrystals ink and apply it to an all-solution-processed approach for the preparation of films with a thickness of approximately 730 nm and with enhanced optical properties and lower band gap energy than the undoped semiconductor films. The low … WebNov 21, 2024 · The largest source of bismuth is found in the mineral bismuthinite, or bismuth sulfide (Bi 2 S 3), according to John Emsley in his book, "Nature’s Building Blocks: An A-Z Guide to the Elements ...
Two new quaternary copper bismuth sulfide halides: CuBi
WebTwo new copper bismuth sulfide halides, CuBi 2 S 3 Cl and CuBi 2 S 3 Br, were synthesized by a two-step process of ball milling followed by annealing. Both compounds are obtained as dark grey powders and crystallize in the monoclinic space group C2/m with lattice parameters abcβ = 91.150(3)° for the sulfide chloride and abcβ = 90.322(4 ... WebOct 15, 2024 · Spray pyrolysis technology for a uniform and high conductive Cu 3 BiS 3 (CBS) electrode was developed in order to carry out the water splitting reaction. A heterojunction photocathode consisting of a p-type Cu 3 BiS 3 and an n-type In 2 S 3 semiconductor was successfully fabricated and further modified by Pt particles for … herbapis
