摘要：
The monodisperse spindle-shaped CeO2 microstructures with irregular surface and the sharp ends have been successfully synthesized via a simple hydrothermal method. XRD, SEM, XPS, Raman scattering and photoluminescence (PL) spectrum were employed to characterize the samples. The results showed that the spindle-shaped CeO2 have a fluorite cubic structure and there are Ce3+ ions and oxygen vacancies in surface of samples. The synthesized CeO2 shows excellent room temperature optical properties, which is likely associated with Ce3+ ions and oxygen vacancies in the spindle-shaped CeO2 samples.
