摘要
目前纳米稀土发光材料是材料科学领域研究的热点之一,具有广阔的应用前景。钼酸镧是一种重要的功能材料,它不仅可作为快离子的导体催化剂应用于众多领域,还具有良好的稳定性和有效的能量传递等特点,使其成为一种优良的发光的基体材料。因此,采用静电纺丝技术制备稀土离子掺杂La2Mo2O9低维纳米发光材料将是一个有意义、重要的研究课题。
本文中以聚乙烯吡咯烷酮和金属硝酸盐为前驱体,通过溶胶-凝胶过程制备出具有一定粘度的前驱体溶胶,并采用静电纺丝技术制备了PVP/硝酸盐复合纤维及复合纳米带,经过热处理得到了La2Mo2O9、La2Mo2O9：Eu3+、La2Mo2O9：Tb3+、La2Mo2O9：Sm3+、La2Mo2O9：Er3+、La2Mo2O9：Nd3+、La2Mo2O9：Pr3+纳米纤维及多孔纳米带,采用TG-DTA、XRD、FTIR、FESEM、TEM和荧光光谱等技术对样品进行了表征。结果表明,所制备的稀土离子掺杂的La2Mo2O9纳米纤维尺寸均一,彼此没有交联,纤维直径平均为180-220 nm,长度大于100μm。所制备的稀土离子掺杂的La2Mo2O9纳米带为多孔结构,宽厚比大,平均带宽5-7μm,厚度约130-280 nm,长度大于500μm。获得了一些有意义的研究结果,为进一步深入研究稀土离子掺杂的La2Mo2O9发光纳米材料的性质奠定了一定的基础。
Currently, nano rare earth luminescent materials is hot focus for the aspect of material science research, and it is wide range of application prospects for its unique properties.The lanthanum molybdenum is an important functional material, because it is not only applied to many areas of the catalysts as fast ionic conductors, and also has good stability and effective energy transfer characteristics, making it to become an excellent luminous matrix material. Therefore, fabrication of rare earth ions-doped La2Mo2O9 low-dimensional luminescent nanomaterials via electrospinning will be a meaningful subject of significance.
In this dissertation, sol-gel process was applied to prepare the precursor sol of certain viscosity using PVP and various nitrate salts as starting materials, and electrospinning technique was used to fabricate PVP/nitrate composite nanofibers and composite nanobelts. La2Mo2O9, La2Mo2O9:Eu3+, La2Mo2O9:Tb3+, La2Mo2O9:Sm3+, La2Mo2O9:Er3+, La2Mo2O9:Nd3+, La2Mo2O9:Pr3+ nanofibers and porous nanobelts were fabricated by calcination of the as-prepared composite nanofibers and composite nanobelts. The samples were characterized by thermogravimetric-differential thermal analysis (TG-DTA), x-ray diffractometry (XRD), Fourier transform infrared spectrometry (FTIR), field emission scanning electron microscope (FESEM), transmission electron microscope (TEM) and fluorescence spectroscopy. The results showed that the diameters of as-prepared rare earth ions-doped La2Mo2O9 nanofibers were in narrow range, and there is no cross-linking among nanofibers, and the diameter was about 180-220 nm, and the length was greater than 100μm. The structure of as-prepared rare earth ions-doped La2Mo2O9 nanobelts with large width-to-thickness ratios were porous, the width of nanobelts were 5-7μm, and the thickness were ca.130-280 nm, and the length was greater than 500μm. Some meaningful results were obtained, and laid solid foundations for the future study of luminescence or up-conversion luminescence of rare earth ions-doped La2Mo2O9 low-dimensional nanomaterials.
