Forbidden-band-width of mono-clinic phase of bismuth vanadate (mBiVO4) is high enough to 2.3-2.4 eV, it could be valence band to carry out entirely that hole band degrade organic pollutants,and the conduction band possesses high oxidizability to make for reduction of photoinduced electron,and oxidation potential of its valence band with 2.4 eV nearby could achieve decomposition of water and degradation of organic pollutants under visible light.

单斜晶相钒酸铋(mBiVO4)的禁带宽度为2.3 - 2.4 eV，它足够高的价带完全可以实现空穴对有机污染物的降解，并且导带位置也有利于光生电子的还原，具有较高的氧化能力，且其价带氧化电位位于2.4 eV附近，可实现在可见光下分解水和降解有机污染物。本文综述了mBiVO4应用于降解污染物、光解水产氧以及光电化学分解水的研究概况，及其在光催化降解有机物等领域的应用前景。

We found out one kind of new orange-red long afterglow material La2O2S: Eu3+, Mg, Zr.2 In the phosphor Gd2O2S, Mg, Ti which was prepared by high-temperature solid-state method, the orange afterglow phenomenon can be seen after illuminated with UV light.3 Using the high-temperature solid-state method, Gadolinium oxysulfide phosphors doped with rare earth ions were synthesized. We can observe the red or orange phosphorescence in Gd2O2S doped with Eu3+, Sm3+, Tm3+, Yb3+, Dy3+, Er3+, Nd3+or Ho3+. This is a new result of the long afterglow phosphors research.4 Using the microwave radiation method, the new Sm3+ doped gadolinium oxysulfide phosphor, which has the orange-red long afterglow emission after illuminated with UV light or visible light, was synthesized for the first time.5 In fluorescent materials YOX doped with europium ions, the long afterglow phenomenon wasnt observed but the blue luminescence of Eu2+ and red luminescence of Eu3+ are simultaneously examined. This is a new result of the valence stability and change of Eu2+ in yttrium oxyhalide .We systematically studied the effects of the host, addition agents and reaction atmosphere on the valence change and fluorescence property of europium ions.
