Ultrasonic-assisted microwave synthesis of luminescent V2O5/MgF2:Eu3+ and its catalytic properties

We used ultrasonic-assisted microwave technique to synthesize V 2 O 5 /MgF 2 :Eu 3+ with characteristic red emissions. Phototocatalytic performances and emission properties were improved compared to the traditional route. Further investigation indicates that 9% V 2 O 5 (molar ratio V/Mg=9%) gave the best result for decomposing methylene blue (91% in 1   h).
