本文用分光光度法研究了 Nd~(3+)、Ho~(3+)离子同1—苯基—3—甲基—4—三氟乙酰基吡唑酮—5(PMTFP)和二苯胍(DPG)所形成的三元配合物的超灵敏跃迁现象;试验了该体系在光吸收最大时遵守比耳定律的浓度间隔;确定三元配合物的组成比为 Ln~(3+):PMTFP:DPG=1:4:1;研究了固态三元配合物的红外吸收光谱和热稳定性。
In this paper, the effects of Nd ~ (3 +), Ho ~ (3+) ions and 1-phenyl-3-methyl-4-trifluoroacetylpyrazolone-5 (PMTFP) (DPG) formed ternary complexes of ultra-sensitive transition phenomenon; test the system at maximum light absorption to comply with the Beer’s law concentration interval; determined ternary complex composition ratio Ln ~ (3 +): PMTFP : DPG = 1: 4: 1; The infrared absorption spectra and thermal stability of the ternary complex were studied.
