摘要
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。
LiMgAlF 6 with the ratio 120/100/110 of LiF/MgF 2/AlF 3 was synthesized by high temperature solid state reaction at 735℃ in Ar stream.Its crystal structure was determined by XRD It belong to hexagonal.The luminescence properties of Ce 3+ ,Eu 3+ ,Gd 3+ ,Tb 3+ and sensitization of Ce 3+ to Tb 3+ have been studied. It was shown that energy transfer between Ce 3+ and Tb 3+ is efficient.
