采用７３５℃高温固相反应，在高纯Ａｒ气保护下、配比为ＬｉＦ∶ＭｇＦ２∶ＡｌＦ３＝１２０∶１００∶１１０时合成了ＬｉＭｇＡｌＦ６。用Ｘ射线确定其结构为六方晶系。研究了ＬｉＭｇＡｌＦ６中掺Ｃｅ３＋、Ｅｕ３＋、Ｇｄ３＋和Ｔｂ３＋的光谱特性。发现Ｃｅ３＋对Ｔｂ３＋有明显的敏化作用。
Using high-temperature solid-state reaction of 735 ℃, LiMgAlF6 was synthesized under high purity Ar gas with the ratio of LiF:MgF2:AlF3 = 120: 100:110. X-ray was used to determine the structure of the hexagonal system. The spectral characteristics of Ce3 +, Eu3 +, Gd3 + and Tb3 + doped in LiMgAlF6 were studied. Ce3 + was found to sensitize Tb3 +.
