Аннотация: Up-conversion (UC) phosphors Gd2(WO4)3:Er3+/Yb3+ were synthesized by a high temperature solid-state reaction method. The crystal structure of Gd2(WO4)3:3% Er3+/10% Yb3+ was refined by Rietveld method and it was showed that Er3+/Yb3+ were successfully doped into the host lattice replacing Gd3+. Under 980 nm laser excitation, intense green and weak red emissions centered at around 532 nm, 553 nm, and 669 nm were observed, which were assigned to the Er3+ ion transitions of 4H11/2 → 4I15/2, 4S3/2 → 4I15/2 and 4F9/2 → 4I15/2, respectively. The optimum Er3+ doping concentration was determined as 3 mol% when the Yb3+ concentration was fixed at 10 mol%. The pump power study indicated that the energy transfer from Yb3+ to Er3+ in Er3+, Yb3+ co-doped Gd2(WO4)3 was a two-photon process, and the related UC mechanism of energy transfer was discussed in detail.
