The study of the influence of different substances introduced on the same matrix will provide a good guide for the construction of materials with good properties. A series of transitions/lanthanides metal ions doped or co-doped Al2O3 aerogel materials with three-dimensional nano porous structure were fabricated by a simple and facile modified sol-gel method. The effect of different transitions/lanthanides metal ions on the microstructure, textural properties, and luminescence properties of Al2O3 aerogels were investigated. By co-doping the Al2O3 aerogel matrix with Eu3+ and Tb3+, we fabricated Al2O3 aerogel luminescent materials with tunable color emissions under UV excitation. The characterization results showed that the microscopic morphology of these aerogels induced by transitions/lanthanides metal ions were obviously different. Interestingly, Al2O3-Eu/Tb (III) and Al2O3-Tb/Ce (III) aerogels exhibited a special flower-like structure. It is hoped that our work will offer some efforts for the preparation of functional materials with excellent properties.

不同过渡金属/镧系金属离子诱导Al2O3气凝胶复合材料的合成及微观结构

研究不同物质对同一基体的影响,将为构建具有良好性能的材料提供良好的指导。采用简单易行的改性溶胶-凝胶法制备了一系列具有三维纳米多孔结构的过渡/镧系金属离子掺杂或共掺杂的Al 2 O 3气凝胶材料。研究了不同过渡/镧系金属离子对Al 2 O 3气凝胶的微观结构、织构性能和发光性能的影响。通过用Eu 3+和Tb 3+共掺杂Al 2 O 3气凝胶基质,我们制造了Al 2 O3 种气凝胶发光材料在紫外线激发下具有可调颜色发射。表征结果表明,过渡/镧系金属离子诱导的这些气凝胶的微观形貌明显不同。有趣的是,Al 2 O 3 -Eu/Tb (III) 和Al 2 O 3 -Tb/Ce (III) 气凝胶表现出特殊的花状结构。希望我们的工作能为制备具有优异性能的功能材料做出一些努力。
