| 摘 要： | 采用溶胶-凝胶法结合气氛控制的技术制备了AgIn合金量子点掺杂钠硼硅基(NBS)玻璃。利用X射线粉末衍射仪(XRD)、X射线光电子能谱(XPS)、高分辨透射电子显微镜(HRTEM)以及选区电子衍射(SAED)对AgIn合金量子点在玻璃中的形貌和微结构进行了表征, 并利用荧光光谱仪对该玻璃的荧光性质进行了研究。结果表明, 在600℃热处理下钠硼硅玻璃中形成了尺寸分布在5 nm左右的均一的AgIn六方晶系量子点, 而且分布在玻璃中的AgIn量子点在435 nm附近存在一个荧光峰, 表明AgIn量子点掺杂NBS玻璃可以作为激光源、非线性介质和光子设备的候选玻璃。

| Abstract: | Indium-silver alloy quantum dots doped sodium borosilicate (NBS) glass was prepared by Sol-Gel method with controlled atmosphere technology. The morphology and microstructure of AgIn alloy quantum dots in the glass were characterized by means of X-ray powder diffraction (XRD), X-ray photoelectron spectroscope (XPS), high- resolution transmission electron microscope (HRTEM) and electron diffraction (SAED). The fluorescent properties of the glass by fluorescence spectrometer were studied. The results showed that indium-silver alloy quantum dots with an average grain size of 5 nm were finely dispersed in the sodium borosilicate glass after heat-treated at 600℃. Indium- silver alloy quantum dots in the glass exhibited a fluorescence peak at around 435 nm which nominated AgIn quantum dots doped NBS glass as the candidate glass for laser sources, nonlinear media and photonic applications. |
