By exploiting colloidal properties, such as transparency, rheology and versatile chemistry, we propose to synthesize new photonic nanomaterials based on colloidal solutions and thin films. This contribution highlights our efforts to elaborate and to characterize nanostructures based on the ZnO-TiO system. Using a recently developed sol-gel route to synthesize new Ti@ZnO organosols, we were able to prepare, at relatively low temperature (400 °C) and short annealing time (15 min), highly transparent, luminescent, nanocrystalline Eu doped c-ZnTiO thin films. The organosols and thin films were characterized with UV-visible-near infrared absorption, ellipsometry, photoluminescence spectroscopy, dynamic light scattering, x-ray diffraction and scanning electron microscopy.
通过利用诸如透明度、流变学和多样化学性质等胶体特性，我们提议合成基于胶体溶液和薄膜的新型光子纳米材料。本论文突出了我们在制备和表征基于ZnO-TiO体系的纳米结构方面所做的努力。使用最近开发的溶胶-凝胶路线合成新型Ti@ZnO有机溶胶，我们能够在相对较低温度（400°C）和较短退火时间（15分钟）下制备出高透明、发光的纳米晶Eu掺杂c-ZnTiO薄膜。通过紫外-可见-近红外吸收、椭偏仪、光致发光光谱、动态光散射、X射线衍射和扫描电子显微镜对有机溶胶和薄膜进行了表征。
