Solid Solution in Pseudobinary System Ba2YMoO6–[Ba2YCuO5]

Abstract

Polycrystalline samples of the pseudobinary system Ba₂YMoO₆–[Ba₂YCuO₅] were synthesized using the gel combustion method. The obtained samples were investigated using X-ray diffraction and photoluminescence spectroscopy. The substitution of Mo with Cu led to the stabilization of cubic phases Fm3̅m and F4̅3m of the solid solution Ba₂YMo_{1 – x}Cu_xO_{6 – δ} (0 ≤ x ≤ 0.5) in air.
