摘要
合成了稀土（ＲＥ）二苯甲酰甲烷（ＤＢＭ）配合物ＲＥ（ＤＢＭ）３·Ｈ２Ｏ（ＲＥ＝Ｓｍ、Ｅｕ、Ｔｂ、Ｄｙ、Ｐｒ、Ｎｄ、Ｇｄ、Ｙ），用红外光谱、紫外光谱及差热热重谱对其进行了表征，用透射电镜观察了该配合物微晶尺寸，并研究了配合物在固态时的荧光光谱．结果表明该系列配合物微晶的尺寸在５０～２５０ｎｍ之间，在ＲＥ（ＤＢＭ）３·Ｈ２Ｏ（ＲＥ＝Ｓｍ、Ｅｕ）中可观察到较强的稀土离子的特征发射，而在ＲＥ（ＤＢＭ）３·Ｈ２Ｏ（ＲＥ＝Ｔｂ。
The micro-crystal of rare earths (RE 3+ )with dibenzoylmethane(DBM)having the compositions RE(DBM) 3·H 2O(RE=Sm、Eu、Tb、Dy、Pr、Nd、Gd、Y)were synthesized in solution. The micro-crystal were characterized by IR,UV,TG-DTA and TEM examinations. The samples size were from 50 nm to 250 nm region. The fluorescence spectra of the micro-crystal have been investigated. The RE(DBM) 3·H 2O (RE= Eu、Sm)exhibited principally bright characteristic lines of the ions.
