Mixed Metal Oxide Chalcogenides

Mixed metal oxide chalcogenides find utility in a variety of areas, including transparent conductors. BiCuOSe was prepared at low temperature (250 oC) and pressure (< 20 atm) and the experimental parameters (pH, temperature, reagents, etc.) conducive to the hydrothermal preparation of oxide chalcogenides were explored.
