© 2015 Wroclaw University of Technology. Shuttle-like BaMoO 4 microstructure has been successfully synthesized from Ba(N0 3 ) 2 ·4H 2 0 and Na 2 MoO 4 ·2H 2 O as starting materials in ethylene glycol solvent containing 20 mL 5 M NaOH by microwave radiation at 180 W for 30 min. The as-synthesized BaMoO 4 product was characterized by X-ray diffraction (XRD), Fourier transform infrared (FT-IR) spectroscopy, Raman spectrophotometry, scanning electron microscopy (SEM), transmission electron microscopy (TEM) and photolumines-cence (PL) spectroscopy. XRD patterns revealed that the products was tetragonal BaMoO 4 phase. SEM and TEM characterization showed that the product had a shuttle-like BaMoO 4 microstructure. PL of the shuttle-like BaMoO 4 microstructure showed a maximum emission at 466 nm excited by 280 nm wavelength.
