制备了含有Eu(III)络合物的发光聚合物(PMMA)，其具有快辐射速率和高发光量子效率(75±5%)，(双三苯基膦氧化物)(三六氟乙酰丙酮)铕(III)(Eu(hfa)3(TPPO)2)。发光聚合物的量子产率和辐射率分别为75±5%和1.1×103s−1。还利用聚苯基倍半硅氧烷（PPSQ）制备了Eu（III）络合物掺杂聚合物薄膜，构建了波导稀土激光器。我们提出了一种针对稀土激光的发光 Eu(III) 配合物的分子设计策略。
Luminescent polymer (PMMA) containing a Eu(III) complex with a fast radiation rate and a high luminescence quantum efficiency (75±5%), (bis-triphenylphosphineoxide)(tris-hexafluoroacetylacetonato)europium(III) (Eu(hfa)3(TPPO)2), was fabricated. The quantum yield and the radiation rate of the luminescent polymer were found to be 75±5% and 1.1×103s−1, respectively. An Eu(III) complex-doped polymer thin-film was also prepared by use of polyphenylsilsesquioxane (PPSQ) to construct a waveguide lanthanide laser. We propose a strategy for the molecular design of luminescent Eu(III) complexes aiming at lanthanide lasing.
