Abstract

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.
