Introducing of anomalous valence ion in ionic conductive glass for the fiber amplifier

在本研究中，我们尝试在氧化玻璃中引入异常价态离子。我们不能通过电化学反应证实在玻璃中引入了Fe4+、Cr4+、Mn4+等高价过渡金属离子。但在磷酸铁钠玻璃中，我们发现了新的晶体材料，它是钠离子电池的正极活性材料。此外，我们还成功地用钠嵌入法制备了磷酸锡玻璃中的金属锡纳米颗粒。因此，电化学插入工艺适用于氧化玻璃中纳米金属颗粒的形成。

In this study we tried to introduce anomalous valence state ions in oxide glass. We could not confirmed to introduce higher valence transition metal ions such as Fe4+, Cr4+, Mn4+ in glass by electrochemical reaction. But in sodium iron phosphate glass we found new crystalline materials, which plays cathode active materials for sodium ion batteries. Furthermore we succeeded to fabricate tin-metal nano particles in tin phosphate glass by sodium intercalation. Therefore electrochemical insertion process is suitable for the formation of nano metal particle in oxide glass.
