摘要：
The polygonal CeO2 nanosheets have been successfully synthesized by a facile hydrothermal technique. XRD, SEM, TEM, XPS, Raman scattering, photoluminescence (PL) spectra, and M–H curve were employed to characterize the samples. The results showed that there are Ce3+ ions and oxygen vacancies in the surface of CeO2 nanosheets with a cubic fluorite structure. It is found that the polygonal nanosheets of 0.5–1.5 µm in diameters and about 50 nm in thickness display a wafery centre with some cracks. The magnetic and photoluminescence measurements indicated that the CeO2 nanosheets exhibit excellent ferromagnetism and optical properties at room temperature, which is likely attributed to the effects of the Ce3+ ions and oxygen vacancies.
