Controllable route to barium molybdate crystal and their photoluminescence

A simple precipitation route has been developed to synthesize BaMoO4 with different morphologies, such as flower-like spheres, spindle-like and octahedron crystals, by using a novel organic compounds poly-(styrene-alt-maleic acid) (PSMA) as crystal growth modifier. The concentrations of PSMA and reactants have significant influences on the morphology control of BaMoO4. PSMA efficiently controls the morphology by inhibiting the oriented growth direction. The photoluminescence spectra show broad green emission at 530 nm, which is attributed to the T-1(2) -> (1)A(1) transition in the intrinsic MoO42 group. (C) 2015 Elsevier B.V. All rights reserved.
