Eu-doped Y2O3 nanosheets and nanotubes

Abstract

A hydrothermal method was used to synthesize Eu-doped Y2O3 nanosheets and nanotubes. High Resolution transmission electron microscopy (HRTEM) and synchrotron x-ray diffraction were used to characterize these nanomaterials. The nanosheets were obtained using a slightly lower pH value and they were partly crystalline and partly amorphous. Using a pH value of about 10, fully crystalline nanotubes were obtained. It is anticipated that nanosheets folded themselves to form stable nanotubes.
