| 摘 要： | 利用大豆卵磷脂在水中自发形成的囊泡作模板, 先制备出含有Eu3+的卵磷脂乳液, Eu3+与卵磷脂亲水头部的磷氧键相结合形成Eu—O—P键, 经用NH4F沉淀后制得前驱体, 该前驱体在600 ℃灼烧, 得到EuF3纳米线, 其直径约为10-20 nm. 通过对各阶段产物的荧光光谱、傅里叶变换红外(FTIR)光谱、热重-差热分析(TG-DTA)、透射电镜(TEM)等的对比分析, 确认形成了Eu—O—P键, 所得到的纳米线是多晶相EuF3.

| Abstract: | The precursor was prepared in two steps: the soybean lecithin latex containing Eu3+ ions was prepared first using a EuCl3 solution. The vesicles formed spontaneously in the soybean lecithin aqueous solution and were used as a template. The precursor was then obtained by precipitating Eu3+ ions with NH4F in the vesicle system that was formed by soybean lecithin. EuF3 nanowires with diameters of about 10-20 nm were obtained from the precursor that was annealed at 600 ℃. The formation of the EuF3 nanowires is discussed considering a comparative analysis by fluorescence spectra, Fourier transforminfrared (FTIR) spectra, thermal gravimetric analysis-differential thermal analysis (TGA-DTA), and transmission electron microscopy (TEM) of the products from each stage. Results show that the Eu—O—P bond is formed by the coordination of Eu3+ ions and the nanowires are multi-crystalline phase EuF3. |
