摘要: 以商业硅酸盐玻璃为原材料，在170˚C下，通过简单的低成本一步水热法成功制备了SiO2纳米棒。SEM结果显示，氨水浓度和保温时间在SiO2纳米棒的形成中都起着重要的作用。XRD结果证实了合成的SiO2纳米棒为非晶结构。光致发光结果表明合成的纳米棒在410 nm表现出强烈尖锐的发射峰。
Abstract: SiO2 nanorodes were successfully synthesized by a simple low-cost one-step alkaline hydrothermal process using commercial silicate glass at 170˚C. The SEM results show that ammonia concentration and holding time play an important role in the formation of SiO2 nanorods. XRD results confirmed that the synthesized SiO2 nanorods were amorphous. Photoluminescence results showed that the synthesized nanorodes exhibited a strong, sharp photoluminescence emission peak, centered at 410 nm.
