| 摘 要： | 利用乙酰丙酮铟为前驱体,甲苯溶剂热方法制备了具有级次结构的新型花状立方氧化铟,纳米花由粒径为3-5 nm的纳米颗粒组成。通过X-射线粉末衍射（XRD）技术、红外光谱（FT-IR）、透射电子显微镜（TEM）、高分辨透射电子显微镜（HR-TEM）等技术对其进行了表征。这种In2O3花状纳米结构具有独特的发光性质,发射中心分别处于438 nm（蓝）、546 nm、569 nm（黄）、618 nm（橙）处。

| Abstract: | A simple solvothermal route based on indium complex as precursor was developed to synthesize 3-dimensional（3D） hierarchical flowerlike nanostructure.Indium oxide with the same flowerlike hierarchical structure was directly obtained in one-step.The In2O3 nanoflowers are well dispersed,have a uniform diameter of ca.30-50 nm nm,and are composed of nanoparticles of ca.3-5 nm size.The photoluminescence（PL） spectra were used to characterize the products.It is observed that the PL spectrum of In2O3 naoflowers at room temperature exhibit peaks centered at 438 nm（blue）,546 nm,569 nm（yellow）,618 nm（orange） in the range of visible light. |
