The chemical effects of high intensity ultrasound and microwave irradiation on lanthanide (Eu(3+), Tb(3+), Sm(3+) and Dy(3+)) activated SrWO(4) 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, Sm(3+), Dy(3+) and Eu(3+) 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 dyes.
本研究广泛考察了高强度超声和微波辐照对镧系元素（Eu(3+)、Tb(3+)、Sm(3+)和 Dy(3+)）激活的 SrWO(4)荧光粉的化学效应。通过在 70°C 下仅 45 分钟的极短时间内，我们简便地制备出了具有显著发光性能的四大类特征光学活性材料（红色、绿色、橙红色和蓝黄色）。特别地，Sm(3+)、Dy(3+)和 Eu(3+)掺杂的 SrWO(4)化合物在可见光激发下具有发光性能。通过研究不同染料的降解行为，系统地考察了这些发光镧系掺杂钨酸盐的光催化性能。
