Microwave-assisted synthesis, characterization and photoluminescence of shuttle-like BaMoO₄ microstructure

Shuttle-like BaMoO₄ microstructure has been successfully synthesized from Ba(N0₃)_2·4H₂0 and Na₂MoO_4·2H₂O 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 BaMoO₄ 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 photolumines­cence (PL) spectroscopy. XRD patterns revealed that the products was tetragonal BaMoO₄ phase. SEM and TEM characteriza­tion showed that the product had a shuttle-like BaMoO₄ microstructure. PL of the shuttle-like BaMoO₄ microstructure showed a maximum emission at 466 nm excited by 280 nm wavelength.
