中文摘要:

一个维的锶 hydroxyapatite (Sr 幸运) nanorods 被一个简单 solvothermal 方法成功地综合。产品经由 X 光检查衍射(XRD ) 被描绘, Fourier 变换红外线(英尺红外) ,冷地排放扫描电子显微镜学(FESEM ) ,传播电子显微镜学(TEM ) ,光致发光(PL ) 刺激和排放系列。试验性的结果显示表面活化剂在限制 Sr 幸运的生长起了一个关键作用的油的酸搽粉。一个维的 nanorod 的可能的形成机制被建议并且详细描述。而且,同样获得的 Sr 幸运样品给在长波长的紫外轻刺激和在有的合成过程使用的 NaOH 的内容下面在 460 nm 集中的一个强烈、明亮的排放乐队看了 Sr 幸运的光表演上的明显的影响搽粉。Sr 幸运样品的可能的光机制被讨论。

英文摘要:

One-dimensional strontium hydroxyapatite (Sr-HAp) nanorods were successfully synthesized by a simple solvothermal method. The products were characterized via X-ray diffraction (XRD), Fourier transform infrared (.FT-IR), .cold field emission.sc.anning.elec.tron microscopy_.(FESEM), transmission.electron microscopy (TEM),photoluminescence (PL) excitation and emission spectra. The experimental results indicated that oleic acid as a surfactant played a key role in confining the growth of the Sr-HAp powders. A possible formation mechanism of the one-dimensional nanorod was proposed and elaborated. Moreover, the as-obtained Sr-HAp samoles showed an intense and bright emission band centered at 460 nm under long-wavelength UV light excitation and the contents of NaOH used in the synthetic process had an obvious impact on the optical performance of Sr-HAp powders. The possible luminescent mechanism of the Sr-HAp samples was discussed.
