摘要

In this paper, Ho3+/Yb3+ co-doped Bi2WO6 (Ho3+/Yb3+-Bi2WO6) nanoparticles were successfully synthesized by a facile hydrothermal method followed by a heat treatment process. X-ray diffraction, field emission-scanning electron microscopy, energy dispersive spectroscopy and up-conversion luminescence spectra were used to characterize the as-synthesized Ho3+/Yb3+-Bi2WO6. The effects of Yb3+ concentration on up-conversion luminescence properties were investigated. Under 980 nm laser excitation, two emission peaks centered at 546 nm and 655 nm corresponding to the F-5(4), S-5(2) and F-5(5) transitions, respectively, to the I-5(8) ground state were observed. Power studies revealed that a two-photon process was involved in the up-conversion emissions and the probable up-conversion emission mechanisms were discussed according to the energy transfer process. This study confirms that Bi2WO6 could be a potential host to achieve desired up-conversion luminescence and might be potentially applied in the fields of photocatalysis and solar cells.
