【摘要】采用水热法合成了ZnWO4纳米棒,并用扫描电镜(SEM)、透射电镜(TEM)和粉末X射线衍射(XRD)等技术对产物进行了表征.实验结果表明,反应溶液的pH值和反应时间是影响ZnWO4纳米棒形成的重要因素.研究了不同反应条件下制备的ZnWO4纳米晶的光致发光性能.更多还原

【Abstract】 ZnWO4 nanorods were prepared via a hydrothermal route,and characterized by X-ray diffraction(XRD),transmission electron microscopy(TEM),and scanning electron microscopy(SEM).The morphology of ZnWO4 nanocrystals were found to depend on the reaction time and pH.Luminescent properties of ZnWO4 nanocrystals were investigated by photoluminescence(PL)spectroscopy.更多还原
