通过过氧化途径,在低温(100℃)且不使用模板和有机溶剂的条件下,成功制备了具有良好荧光性能的三氧化钼(MoO3)纳米带水溶胶.利用X射线衍射仪(XRD)、透射电子显微镜(TEM)、高分辨透射电子显微镜(HRTEM)、荧光光谱仪、荧光显微镜等表征手段对所制备溶胶的结构及性能进行了表征.结果显示,溶胶是由长度约为100μm,宽度为50 nm到100 nm,厚度小于10 nm的MoO3纳米带组成.所制备的溶胶烘干后可以得到大面积的MoO3纳米带薄膜,薄膜具有很好的韧性.荧光光谱图及荧光显微镜照片显示,纳米带溶胶及干燥后所得到的自支撑(free standing)纳米带薄膜均具有良好的荧光性能,表明其在光学成像、传感及LED等方面具有很好的应用前景.
