在P=7 Gpa，700℃的高压条件下合成了一种新的Bi3-Ge(3)O(10.5)化合物，取代了通常在高压下稳定的焦绿石，其晶体结构为KSbO(3)-YPE。用Rietveld方法从同步辐射X射线衍射数据中对晶体结构进行了修正。此外，我们还用X射线光电子能谱、光致发光和比热等手段对Bi3+Ge(3)O(10.5)进行了表征。
A new Bi(3)Ge(3)O(10.5) compound has been synthesized under high pressure, P = 7 GPa, and 700 °C. Instead of the pyrochlore that is normally stabilized under high pressure, the Bi(3)Ge(3)O(10.5) crystallizes in a KSbO(3)-ype crystal structure. The crystal structure has been refined by the Rietveld method from synchrotron X-ray diffraction data. Moreover, we have also characterized the Bi(3)Ge(3)O(10.5) by X-ray photoelectron spectroscopy, photoluminescence, and specific heat.
