The characteration of 15 will may provide a new pathfor searching new triboluminescent complexes. The triboluminescence maximum of 15is similar to that of its photoluminescence. The disorder of the thienyl rings and 〓groups in 15 may be responsible for its triboluminescent activity.

Eu的距离为4.2137(9)〓。两个桥联O原子与两个Eu构成一平面四边形，∠Eu(1)-O(7)-Eu(1A)和∠O(7)-Eu(1)-O(7A)分别为117.84(14)°和62.18(14)°。15的摩擦发光光谱与其光致发光光谱很类似，表明它们有相同的激发态。15的摩擦发光活性可能与其结构中噻吩环及〓的无序有关。

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.

Therapeutic horseback riding have been believed as a good media to improve balance ability. We proceeded to do a case study, by the use of a mechanical horse made by Joba EU-6441, Matsushita Electric Industrial Co., Ltd., Japan. This mechanical horse is designed according to the movement pattern of a real horse. The seat is designed to move in a pattern based on the figure of eight. Many clinics begin to adopt the mechanical horses as treatment tools, but its effectiveness in children with ADHD remains unknown.
