BaMO4(M =W, Mo) particles were synthesized successfully using a solid-state metathetic route assisted by a cyclic microwave irradiation. Well-crystallized BaMO4(M=W, Mo) particles were formed at 400-600 oC for 3 h, showing fine and homogeneous morphologies with particle sizes of 1-2 μm. The synthesized BaMO4(M =W, Mo) particles were characterized by X-ray diffraction, Fourier transform infrared spectroscopy and scanning electron microscopy. The optical properties were investigated by photoluminescence emission and Raman spectroscopy.
