中文摘要	trivalent dysprosium (dy3+)-activated beta-gallium oxide (beta-ga2o3) phosphors were synthesized by solid-state (ss), coprecipitation (cp), and citrate gel (cg) methods, respectively. the resulting beta-ga2o3:dy3+ phosphors were well characterized by x-ray diffraction, field-emission scanning electron microscopy (fesem), and by photoluminescence and cathodoluminescence spectra. the phosphors prepared by different methods show different luminescence properties under the excitation of uv and low-voltage cathode rays. there exists an energy transfer from the beta-ga2o3 host lattices to dy3+, and the energy transfer efficiency was higher in the cg-derived phosphors than those of the ss- and cp-derived phosphors. factors influencing the intensity of luminescence and the energy transfer efficiency from beta-ga2o3 host to dy3+ in beta-ga2o3:dy3+ phosphors were investigated in detail. it is shown that the cg method is the most respected process for the preparation of beta-ga2o3:dy3+ phosphors.
