We have reported the preparation of Pt-coated MgO nanowires and investigated changes in the structural and photoluminescence (PL) characteristics resulting from application of a thermal annealing process. Scanning electron microscopy (SEM), X-ray diffraction (XRD), transmission electron microscopy (TEM), and energy-dispersive X-ray spectroscopy (EDX) have been used to characterize the samples. The shell layer was transformed to Pt nanoparticles by thermal annealing at 800 degrees C. We have studied the effects of Pt-coating and thermal annealing on the PL emission of the products. This approach will offer a potentially useful and novel route for the fabrication of a variety of metal nanoparticles on core nanowires.
我们已报道了铂包覆氧化镁纳米线的制备，并研究了热退火工艺对其结构和光致发光（PL）特性的影响。扫描电子显微镜（SEM）、X射线衍射（XRD）、透射电子显微镜（TEM）和能量色散X射线光谱（EDX）已被用于表征样品。通过在800摄氏度下进行热退火，壳层转变为铂纳米颗粒。我们研究了铂包覆和热退火对产物PL发射的影响。这种方法将为在核心纳米线上制备各种金属纳米颗粒提供一条潜在有用的新途径。
