摘要：

Cadmium vanadium oxides (Cd2V2O7) and Cadmium carbonates (CdCO3) were synthesized via a facile hydrothermal method. X-ray diffraction (XRD), Raman spectroscopy, infrared spectrometer (IR), scanning electron microscopy (SEM), high resolution transmission electron microscopy (HRTEM) and X-ray photoelectron spectroscopy (XPS) were employed to characterize the structure, morphology and chemical state of the samples, respectively. The photoluminescence (PL) properties of the as-synthesized Cd2V2O7 and CdCO3 were measured at room temperature using an excitation wavelength of 325 nm. The Cd2V2O7 shows two visible light emission centers located at 589 and 637 nm, which are supposed to be relevant to local defects in Cd2V2O7. The CdCO3 shows three emission centers located at 408, 530 and 708 nm, which are supposed to be relevant to the electron transition from the conduction band to valence band and defect related energy level.
