  Temperature-dependent energy transfer in photo-sensitized luminescence of rare earth complexes

  摘要：

  We have fabricated polymer thin films containing bis(triphenylphosphineoxide)-tris(hexafluoroacetylacetonato) terbium(III) [Tb(HFA)(3)(TPPO)(2)] as a thermo-sensor. The thermo-sensitivity of the thin film containing the Tb(III) complex was found to be 13.5%/degrees C. The emission intensity ratio normalized according to that at 0 degrees C observed for Tb(HFA)(3)(TPPO)(2) in the thin film was not affected by pressure. The thermo-sensing thin film is expected to be useful in measuring surface-temperatures of bodies in wind-tunnel experiments. (c) 2005 Elsevier B.V. All rights reserved.

  spectra of [Gd(3Cl-acac)3(H2O)2], the effect of chloride replacement of hydrogen on the triplet state energy of the 3Cl-acac ligand was revealed. To support the interpretation and rationalization of the experimental results, Time-dependent DFT calculations were performed on Tb(3Cl-acac)3(H2O)2. Additionally, the possibility of Tb(3Cl-acac)3(H2O)2 to be used as potential green-emitting phosphor material for

  α-取代的 β-二酮 [Ln(3Cl-acac)3(H2O)2] [Ln = Tb, Gd] 配合物（3Cl-acac– 是 3-氯-2,4-戊二酸）通过元素分析表征、红外、紫外 (UV) 可见光和光致发光光谱。为了比较光致发光，还合成了众所周知的 [Tb(acac)3( )2] 复合物。通过考虑[Gd(3Cl-acac)3( )2]的磷光光谱，揭示了氯化物置换氢对3Cl-acac配体三线态能量的影响。为了支持对实验结果的解释和合理化，对 Tb(3Cl-acac)3( )2 进行了瞬态 DFT 计算。此外，还评估了 Tb(3Cl-acac)3( )2 用作固态发光二极管的潜在绿色荧光粉材料的可能性。成功地制造了一个原型，用 Tb(3Cl-acac)3( )2 复合物涂覆近紫外 LED（370 nm）。图形概要

  the PA amplitude spectra reflected the variation of the luminescence efficiency and the PA phase is directly relative to the relaxation processes. According to the variation of the luminescence efficiency and the phase shift, the intramolecular energy transfer and relaxation processes of different Tb(III) complexes were discussed.

  测量了不同Tb（III）配合物（Tb（AA）3.2H2O Na [Tb（AA）4]，Tb（AA）3bpy和Tb（AA）3phen）的光声（PA）振幅光谱和发光光谱，并且计算出不同配合物的PA相移。结合发光光谱，PA振幅光谱反映了发光效率的变化，并且PA相位与弛豫过程直接相关。根据发光效率和相移的变化，讨论了不同Tb（III）配合物的分子内能量转移和弛豫过程。
