Abstract—
We have investigated phase relations along a number of joins in the subsolidus region of the Cs2MoO4–BaMoO4–Gd2(MoO4)3 system using X-ray diffraction and differential thermal analysis and constructed its phase compatibility diagram. A ternary molybdate with the composition CsBaGd(MoO4)3 and a monoclinic scheelite-like structure (sp. gr. P21/n) has been synthesized. Codoping CsBaGd(MoO4)3 with Er3+/Yb3+ ions, we have obtained an upconversion phosphor exhibiting anti-Stokes luminescence in the range 400–700 nm under IR excitation (λex = 977 nm). The synthesized phosphor has been characterized by X-ray diffraction, differential thermal analysis, and vibrational spectroscopy, and its luminescence spectrum has been measured.
