在180℃水热处理葡萄糖和铟盐的混合物,然后在空气中烧结制备了氧化铟空心球.利用场发射扫描电镜、透射电镜、X射线衍射等对其形貌和结构进行分析.结果表明,氧化铟空心球为多孔结构,其粒径为800～1000nm,由密堆积的纳米粒子组装而成.讨论了氧化铟空心球的形成机制和光致发光特性.
In2O3 hollow spheres are successfully synthesized by hydrothermal treatment glucose/InCl3 mixtures at 180℃,and calcining in air.The structure and morphology of In2O3 samples are analyzed by X-ray diffraction,scannin g electron microscopy and transmission electron microscopy.The results show that the as-synthesized In2O3 hollow spheres are porous with a diameter of 800～1000nm,assembled by numerous aggregated nanoparticles.The room temperature photoluminescence properties of In2O3 hollow spheres are studied.Furthermore,the growth mechanism is discussed briefly.
