掺杂立方T1I单晶是长期以来探索的新型红外光学材料。由于T1I晶体是个多形变体,在通常条件下只有黄色正交相才能稳定存在。文献所载的T1I溶解度数据,没说明是哪一种构型的测定值。我们在研制出掺杂立方T1I单晶之后,测定它在各类溶剂中的溶解度, Doping cubic T1I single crystal is a new type of infrared optical material that has been explored for a long time. Since the T1I crystal is a polymorphic form, only the yellow orthorhombic phase is stable under the usual conditions. The T1I solubility data contained in the literature did not indicate which configuration was measured. We developed a doped cubic T1I single crystal, the determination of its solubility in various solvents,
