| 摘 要： | 合成了四个系列稀土掺杂铽乙酰丙酮(Hacac)三元配合物RExTb1-x(acac)3phen和RExTb1-x(acac)3bipy(RE=La,Y;x=0,010,020,030,050,070,090,100;phen1,10邻菲罗啉;bipy2,2’联吡啶)。通过红外光谱、X射线粉末衍射对配合物进行了表征。对各系列配合物进行荧光光谱研究,发现La3+,Y3+对Tb3+离子均有荧光增敏作用,并且La3+>Y3+。当x=01～03,多数掺杂配合物比未掺杂铽三元配合物具有更好的发光性能。

| Abstract: | Four series of solid complexes including RE_xTb_~1-x (acac)_3phen and RE_xTb_~1-x (acac)_3bipy (RE=La, Y; x=0, 0.10, 0.20, 0.30, 0.50, 0.70, 0.90, 1.00) were synthesized. These complexes were characterized by IR spectra and XRD. Photoluminescence (PL) properties of these complexes were studied. The relation between their fluorescence intensities and the content of doped ions was also discussed. The experimental results show that the PL intensity of Tb~3+ was sensitized by La~3+ or Y~3+ , and La~3+ is better than Y~3+ in enhancing the fluorescence of Tb~3+ . When x=0.1-0.3, the fluorescence intensities of most doped complexes are stronger than their corresponding pure Tb~3+ complex. |
