Hydrothermal synthesis,characterization and properties of lead chromate 1D nanomaterials

利用水热法在不使用任何表面活性剂的情况下成功制备出了包括纳米棒、纳米线在内的铬酸铅一维纳米材料,通过改变反应温度可以很容易对铬酸铅一维纳米材料的长度和长径比进行调节。运用X射线粉末衍射(XRD)、扫描电子显微镜(SEM)、透射电子显微镜(TEM)和高分辨透射电镜(HRTEM)等对所得产物进行了系统的表征,同时对所制备的铬酸铅一维纳米材料的光学性质进行了研究分析。

Monoclinic PbCrO4 nanorods and nanowires have been successfully synthesized by a simple aqueous solution method without using any surfactants.The length and aspect ratios of the PbCrO4 one dimensional（1D） nanostructures could be easily manipulated by changing the reaction temperature.The as-synthesized products were characterized with X-ray diffraction（XRD）,scanning electron microscopy（SEM）,transmission electron microscopy（TEM）,high-resolution transmission（HRTEM）,and so on.The optical properties of the products were also investigated in detail.
