Abstract
The chemical effects of high intensity ultrasound and microwave irradiation on lanthanide (Eu3+, Tb3+, Sm3+ and Dy3+) activated SrWO4 phosphors were extensively studied. Four classes of characteristic optically active materials (red, green, orange-red and blue-yellow) with striking luminescence were facilely prepared under very low temperature (70 °C) in 45 min. Particularly, Sm3+, Dy3+ and Eu3+ doped strontium tungstates were visible-light driven emissive. The photocatalytic properties of these luminescent lanthanide doped tungstates were systematically examined by investigating the degradation behavior of different
