A new germanate |H₂(C₄N₃H₁₃)|₃[Ge₇O_14.5F₂][Ge₇O₁₄F₃]·2.5H₂O (denoted as JLG-16) has been synthesized by using diethylenetriamine as the structure-directing agent under solvothermal conditions. Single-crystal structural analysis reveals that JLG-16 crystallizes in the monoclinic space group C2/c with a = 38.2008(15) Å, b = 8.8262(4) Å, c = 31.1789(13) Å, and β = 108.5470(10)°. Its structure is made up of 4- and 5-coordinated Ge₇ clusters. The alternating connection of 4- and 5-coordinated Ge₇ clusters gives rise to a double-layered structure with 16- and 10-ring channels and a low framework density (11.2 Ge per 1000 Å³). Carbon dots (CDs) formed in the mother liquid are in situ embedded into the JLG-16 crystals during the solvothermal crystallization process. The resulting CDs@JLG-16 composite thus exhibits excitation-dependent and temperature-responsive photoluminescence performances, which makes it possible to be used in optical temperature sensing.

一种新的二维分层锗酸盐，具有原位嵌入的碳点，用于光学温度感测

新的德国人| H ₂（C ₄ N ₃ H ₁₃）| ₃在溶剂热条件下，使用二亚乙基三胺作为结构导向剂合成了[Ge ₇ O _14.5 F ₂ ] [Ge ₇ O ₁₄ F ₃ ]·2.5H ₂ O（表示为JLG-16）。单晶结构分析揭示了JLG-16结晶的单斜晶系空间群C ^ 2 / C ^与一个= 38.2008（15）A，b = 8.8262（4），C ^ = 31.1789（13）A，和β= 108.5470（10）°。它的结构由4和5配位的Ge ₇簇组成。的4-和交替连接5配位的Ge ₇簇产生了一个双层结构具有16位和10环通道和低的骨架密度（每1000埃的Ge 11.2 ³）。在溶剂热结晶过程中，母液中形成的碳点（CD）原位嵌入JLG-16晶体中。因此，所得的CDs @ JLG-16复合材料表现出依赖于激发和温度响应的光致发光性能，从而有可能用于光学温度感测。
