Abstract: Different sizes of nanocrystalline CeO2 were synthesized and their reflection absorption spectra have been measured.We have measured the surface photovoltage as the function of wavelength by SPStechnique. And the absorption band was resolved to two peaks with different photovoltaic properties. Photovoltaic quantum size effect was observed by FMSPSmeasurement.

Key words: Nanocrystalline CeO2, Surface photovoltage, Quantum size effect
