Rare-earth ternary complexes Tb(1-x)Eu(x)(m-NBA)(3)Phen (X=1, 0.25, 0.5, 0.75, 1.0) were synthesized and characterized by IR, DTA-TG, UV, fluorescent spectra and elemental analysis. It was found that luminescence of Eu(3+) complex was enhanced by doped with Tb(3+). It is proved by TG curve that the complexes are stable, ranging from ambient temperature to 360 degrees C in air. The organic-inorganic combined structural device was fabricated, and the electroluminescence intensity of the combined structural device was improved compared with the device of the purely organic components.
合成了稀土三元配合物Tb(1-x)Eu(x)(间硝基苯甲酸)₃邻菲罗啉（x = 1, 0.25, 0.5, 0.75, 1.0），并通过红外光谱、差示热重分析、紫外光谱、荧光光谱和元素分析对其进行了表征。发现掺杂Tb(3+)可增强Eu(3+)配合物的发光。热重曲线证明该配合物在空气中从室温到360℃是稳定的。制备了有机-无机复合结构器件，与纯有机组分器件相比，复合结构器件的电致发光强度得到了提高。
