Bright photoluminescent neutral complexes having general formula [Ln(tbtz)₃] (Ln = Eu, Tb; tbtz = tris(benzotriazol-1-yl)borate) were obtained by reacting K[tbtz] with EuCl₃ and TbCl₃. The emissions in the visible range, related to the f-f transitions of the trivalent lanthanide ions, are observable upon excitation with wavelengths shorter than 350 nm. The most intense emission bands correspond to the ⁵D₀ → ⁷F₄ transition at 699 nm for the europium complex and to the ⁵D₄ → ⁷F₅ transition at 542 nm for the terbium derivative. The luminescence is in all the cases mostly associated with the antenna-effect from the coordinated tbtz ligands. The synthetic approach was successfully extended to the preparation of the analogous yttrium and gadolinium derivatives. Tricapped trigonal prismatic geometry was attributed to the complexes on the basis of luminescence data and DFT calculations. Highly photoluminescent plastic materials were obtained by embedding small amounts of [Eu(tbtz)₃] or [Tb(tbtz)₃] in poly(methyl methacrylate).

_{通过使 K[tbtz] 与 EuCl 3}和 TbCl ₃反应，获得具有通式 [Ln(tbtz) ₃ ] 的明亮光致发光中性配合物（Ln = Eu, Tb；tbtz = 三（苯并三唑-1-基）硼酸盐）。可见光范围内的发射，与三价镧系离子的 ff 跃迁有关，在波长小于 350 nm 的激发下可观察到。最强烈的发射带对应于铕络合物在 699 nm 处的⁵ D ₀  →  ⁷ F _4跃迁和⁵ D ₄  →  ⁷ F ₅铽衍生物在 542 nm 处的跃迁。在所有情况下，发光主要与协调的 tbtz 配体的天线效应有关。该合成方法成功地扩展到制备类似的钇和钆衍生物。根据发光数据和 DFT 计算，三冠三角棱柱几何形状归因于配合物。通过在聚甲基丙烯酸甲酯中嵌入少量 [Eu(tbtz) ₃ ] 或 [Tb(tbtz) _{3 ] 获得高光致发光塑料材料。}
