【Abstract】 The diffuse reflectance spectra of nanocrystalline Yb2O3 were measured in the UV-vis region. The absorption band in the region from 300 to 500nm was assigned to the O2p→Yb4f transition. The behavior of light-induced charge transfer and photovoltaic properities of nanocrystalline Yb2O3 were investigated with surface photovoltage spectroscopy (SPS) and electric field modulating SPS techniques.更多还原
