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 +.
