Abstract
In the present paper, we synthesized the novel calcium germanate (CaGeO 3 ) microtubes using electrospinning. The wollastonite structure and morphology of the novel CaGeO 3 microtubes have been confirmed by X-ray diffraction and scanning electron microscopy, respectively. The Raman and infrared spectra of this oxide were recorded and analyzed at room temperature. Then, nuclear site group analysis was used to calculate the total number of normal vibrational modes, Raman-active and infrared-active optical phonon modes. • The novel wollastonite-type CaGeO 3 microtubes are produced by electrospinning. • The microstructure, FTIR and Raman spectra are given. • Theoretical vibrational modes are calculated by nuclear site group analysis.
