摘要：合成了稀土配合物Eu(TTFA)₃(TTFA, 2-thenoyltrifluoroacetone)掺杂的树脂型光刻胶薄膜，测定了薄膜的激发光谱和发射光谱。根据Judd-Ofelt理论，由发射光谱获得了Eu³⁺在光刻胶薄膜中的J-O参数Ω₂=24.4×10^-20 cm²,Ω_４=2.8×10^-20 cm²。利用得到的J-O参数计算了光刻胶薄膜中⁵Ｄ₀激发态的辐射跃迁概率(977 s^-1)和辐射寿命(1.02 ms)，同时导出了光刻胶薄膜中Eu³⁺的⁵Ｄ₀→⁷F_J(J=1, 2, 4)跃迁的受激发射截面σ和荧光分支比β。分析表明，Eu³⁺掺杂的光刻胶薄膜具有较长的亚稳态寿命以及较大的受激发射截面，是一种主动放大的光波导薄膜。其发射波长与光刻胶的低吸收损耗区很好地匹配，可用于研发聚合物光波导放大器和激光器。

Abstract：Eu(TTFA)₃-doped resin photoresist polymer film was successfully prepared and the fluorescence properties of the chelate complex were investigated. Based on Judd-Ofelt theory, the optical intensity parameters Ω₂ and Ω_４ derived from the emission spectrum were 24.4×10^-20 cm² and 2.8×10^-20 cm²,respectively, and the total radiative transition rate (977 s^-1) along with the radiative lifetime (1.02 ms) of the ⁵Ｄ₀ excited state were calculated. The stimulated emission cross sections σ and the fluorescence branch ratios β for the ⁵Ｄ₀→⁷F_J(J=1, 2, 4) transitions were also obtained. The analysis indicates that the excited state of Eu³⁺ in the polymer film has a long radiative lifetime and large emission cross section, and the photoresist polymer film is a kind of ideal active amplificatory waveguide material, whose emission wavelength is in accord with the low absorption loss region of the photoresist. Such photoresist polymer film might have extensive application prospect in optical devices, such as polymer optical waveguide amplifiers and lasers.
