Abstract:	MnWO₄ with nano-plates in flower-like clusters was produced from the mists of the solutions containing MnCl₂·4H₂O and Na₂WO₄·2H₂O at different pH values by 300-900 W cyclic microwave radiation. The phase was detected by XRD and SAED, and was in accordance with that of the simulation. The flowers were characterized using SEM and TEM, and their lattice planes using HRTEM. The vibration spectra were characterized using Raman and FTIR spectrometers. Their photoluminescence is at 409-420 nm.

Keywords:	Cyclic microwave-assisted spray synthesis MnWO₄ Nano-plates in flower-like clusters
