【Abstract】

<正> The Y2O3: Yb3+, Er3+ microstructures were fabricated by a hydrothermal method without surfactants. The microstructures structure was characterized by X-ray diffraction (XRD) and scanning electron microscope (SEM, KYKY 1000B). The up-conversion luminescence spectra were studied under 978 nm laser diode excitation. In Yb3+ and Er3+ codoped Y2O3 microcrystals, the relative intensity of green emission became stronger as the morphology of sample changed from wires to films.
