摘要
合成了3个系列稀土掺杂铕-1,3-双[3-(4-甲基苯基)-3-氧代丙酰基]苯(L)-邻菲咯啉(phen)三元配合物(EuxRE1-)x2(L)(3phen)(2RE=La,Y,Gd;x=1.0,0.9,0.8,0.7,0.6,0.5,0.4,0.3,0.2,0.1).通过摩尔电导率、红外光谱对配合物进行了表征.对各配合物系列进行荧光光谱研究,发现La3+,Y3+和Gd3+对Eu3+离子均有荧光增敏作用,其荧光增敏顺序为Gd3+>La3+>Y3+.表1,参17.
Three series of selid complexes of (Eu,RE1-x)2(L)3(phen)2(RE = La, Y, Gd; L = 1,3-bis[3-(4-methyl phenyl)-3--oxopropanoyl]benzene; x = 1.0,0.9,0.8,0.7,0.6,0.5,0.4,0.3,0.2,0.1 ) were synthesized and then characterized by molar conductance and IR spectra. Photolumineseenee properties of these complexes were studied. The relations between their fluorescent intensities and the content of doped ions were also discussed. La3+, Y3+and Gd3+ can sensitize the fluorescence of Eu3+ in the order of Gd^3+ 〉 La^2+ 〉Y3+ 1tab., 17refs.
