摘要：

Eu3+ doped β-Ga2O3 powders were prepared by hydrothermal method. X-ray diffraction, field emission scanning electron microscopy, transmission electron microscopy, Raman spectroscopy, and photoluminescence spectra were used to characterize the structure and properties of β-Ga2O3: Eu3+ powders. The results reveal that the obtained samples are monoclinic β-Ga2O3 powders. Under the excitation of 325 nm He-Cd laser, the strongest emission peak is located at 612 nm, corresponding to the 5D0→7F2 transition of Eu3+. β-Ga2O3:Eu3+ powders have high photocatalytic degradation rate for methyl orange under simulated solar irradiation, and the photocatalytic degradation rate of methyl orange is up to 75% after 2 h degradation. ©, 2015, Chines Academy of Sciences.
