Abstract

Phase-pure BiCuOSe, which is isostructural to the layered p-type transparent conductor LaCuOS, has been synthesized in high yield by a single-step hydrothermal reaction at low temperature (250°C) and pressure (<20 atm). A moderate reaction temperature of 250°C was sufficiently high to solubilize both Bi₂O₃ and Cu₂O and stabilize monovalent copper and low enough to impede the oxidation of dianionic selenium. BiCuOSe exhibits a relatively high electrical conductivity (σ ≈ 3.3 S cm^-1) and a reduced band gap (E_g = 0.75 eV), which compare favorably with the optoelectronic properties of BiCuOS and the cerium-based oxysulfides, CeAgOS and CeCuOS.
