FTIR and Raman Spectroscopy have been studied for investigating the bonding in nanostructures. The surface morphology of the samples was investigated with field emission scanning electron microscopy (FE-SEM) and transmission electron microscopy (TEM). The photolumniscent nature of the samples was ...
用XRD,Raman光谱和DSC研究了Al2(MoO4)3,Cr2(MoO4)3和Fe2(MoO4)3的结构与相变.Al2(MoO4)3,Cr2(MoO4)3和Fe2(MoO4)3在室温下为单斜相, 分别在483 K,673 K和783 K附近转变为正交相.发现MO4四面体的对称和反对称伸缩振动模的频率和相对强度明显受到A3+离子的影响.这些模的软化程度受A3+离子的影响依次...
Further, rGO functionality on the FeMoO4 tubular NFs was confirmed through the Raman scattering spectra. Figure S2 results in the peaks at 816, 904 and 949 cm−1 are assigned to FeMoO4 [28,34]. In addition, with the completion of rGO wrapping, rGO–FeMoO4 NFs displayed additional ...
