本文研究了 In~(3+)(Ln=Pr,Nd,Sm,Eu,Dy,Ho,Er,Tm 和 Yb)-AA-IQ_x 三元络合物系统中超灵敏跃迁的机理。证明随着镧系离子与 AA 及 IQ_x。形成1:4:1的三元络合物,超灵敏跃迁的振子强度增加,其增加的倍数与原子序数及镧系离子的离子半径之间的关系近似呈现“双峰效应”。通过比较电偶极跃迁与磁偶极跃迁的振子强度数值,证实超灵敏跃迁现象主要来自电偶极跃迁。本文还考察了上述络合物系统中超灵敏跃迁的振子强度与 Judd-Ofelt 参数τ_λ(λ=2、4、6)之间的关系。
In this paper, the mechanism of the hypersensitive transition in the In ~ (3 +) (Ln = Pr, Nd, Sm, Eu, Dy, Ho, Er, Tm and Yb) -AA-IQ_x ternary complex system is studied. Prove that with lanthanide ions and AA and IQ_x. The formation of a 1: 4: 1 ternary complex, the super-sensitive transition oscillator strength increased, the increase in the fold and atomic number and lanthanide ion radius of the relationship between the approximately “bimodal effect.” By comparing the dipole transitions with the dipole transitions, it is confirmed that the hyper-sensitive transition mainly comes from the electric dipole transition. The relationship between the oscillator strength and the Judd-Ofelt parameter τ_λ (λ = 2, 4 and 6) of the hyper-sensitive transition in the above complex system is also investigated.
