摘要
                
                    合成了以对叔丁基[6]芳烃(H6L)及DMF为配体,单一稀土RE3+(Sm3+,Dy3+,Tb3+)及混合稀土Tb3+∶Ln3+(Ln3+=Gd3+,Y3+)为中心的5种稀土配合物。对其进行了元素分析、摩尔电导、红外光谱、差热分析、紫外光谱、核磁共振氢谱及荧光性能研究。荧光光谱的测试表明:Tb3+及其掺杂配合物具有较强的特征荧光,荧光惰性离子(Gd3+,Y3+)对Tb3+的荧光有增强作用,其中Y3+的敏化效果明显。
                
                Five solid coordination compounds of rare earths ( Sm^3 + , Dy^3 + and Tb^3 + ) and RE^3 + ( Gd^3 + and y^3 + ) doped Tb^3+ with p-tert-butylcalix [ 6 ] arene (H6L) and DMF were synthesized and characterized. The elemental analysis, molar conductivity, IR spectra, UV spectra , TG-DTA, ^1H NMR spectra and flu-orescence spectra spectra suggested were studied. The fluorescence that the Tb^3+ complex had characteristic luminescence, and its fluorescence intensity was enhanced after doping with Gd^3+ and Y^3+. The sensitization action of Y^3+ was fairly high.
