Highly ordered Prussian blue nanowires with diameter of about 50 nm and length up to 4 m have been fabricated by an electrodepositing technology with two-step anodizing anodic aluminum oxide films. The Mössbauer spectra taken between 15 and 300 K indicate that the hyperfine parameters decrease as the temperature increases. The temperature dependence of the quadrupole splitting, the isomer shift and the spectra area are discussed. A decrease of Debye temperature for Prussian blue nanowires was found with respect to that of Prussian blue bulk. 相似文献

碳纳米管的拉曼光谱及其温度效应 总被引:3,自引:2,他引:1
在室温下首次观察到碳纳米管的四级拉曼光谱,并且发现碳纳米管的D峰和D*峰的斯托克斯线和反斯托克斯线频率不一致。此外,还发现碳纳米管的拉曼特征峰频率严重依赖样品的温度,随着温度增加,碳纳米管拉曼特征峰频率下移,频移与温度变化成线性关系。 相似文献

碳纳米管和高取向热解石墨的拉曼光谱对比研究 总被引:2,自引:2,他引:0
同时测量了碳纳米管(D-CNT)和高取向热解石墨(HOPG)的拉曼光谱,第一次分别在HOPG和D-CNT中观察到了位于4265cm-1和4248cm-1的(G+D*)三级模的拉曼散射;拉曼谱的研究显示,D-CNT的结构比HOPG的无序,同时也进一步表明此无序程度主要来源于结构的缺陷,而非石墨层卷曲成筒状之故 相似文献
