【摘要】 合成了高氯酸镝二苯亚砜Ｄｙ（ＤＰＳＯ）６（ＣｌＯ４）３、六氟磷酸镝二苯亚砜Ｄｙ（ＤＰＳＯ）７（ＰＦ６）３、高氯酸镝苯丁基亚砜Ｄｙ（ＰＢＳＯ）６（ＣｌＯ４）３三个配合物．测定了配合物的组成、摩尔电导及粉晶荧光激发和发射光谱，根据光谱实验结果计算了配体的Ｓ１及Ｄｙ３＋的第一激发态及基态能级．通过对三个配合物的荧光发射光谱的研究知：Ｄｙ（ＤＰＳＯ）６（ＣｌＯ４）３的发光强度最高，其中４Ｆ９２→６Ｈ１５２谱带强度高达１０６６ｃｄ．表明ＤＰＳＯ配体受激发后可将能量有效地传递给Ｄｙ３＋，另外在一定的条件下阴离ＣｌＯ－４可以增强Ｄｙ３＋的发光性能更多还原

【Abstract】 Dy(DPSO) 7 (PF 6) 3, Dy(DPSO) 6(ClO 4) (ClO 4) 2 and Dy(PBSO) 6(ClO 4) (ClO 4) 2 (DPSO as the abbreviation to diphenyl sulfoxide.PBSO to phenyl butyl sulfoxide) have been synthesized.The coordination compounds have been studied by means of composition analysis,molar conductivity and fluorescent excitation and emission spectra. 4F 9/2 , 6H j/2 (j=13,11) energy level of Dy 3+ and energy levels of ligand have been calculated according to the fluorescent spectra results.In the fluorescent experiments it was found that the fluorescent emission intensity of Dy 3+ ion in Dy(DPSO) 6(ClO 4) (ClO 4) 2 is the highest and 4F 9/2 → 6H 15/2 fluorescence emission intensity is 1 066 cd.The results show that the excitation energy of DPSO ligand is very easily transferred to Dy 3+ ion in Dy(DPSO) 6(ClO 4) (ClO 4) 2 coordination compounds.In addition,ClO - 4 canbe enhanced fluorescence emission of Dy 3+ to a certain degree.更多还原
