摘要

Different concentrations of TiO_2 co-doped NaYF_4: 15 % Yb~(3+), 2 % Er~(3+) powder phosphors were synthesized by the high temperature solid state reaction process. The samples were investigated by X-ray diffraction, scanning electron microscopy and photoluminescence testing. The results show that, under the 980 nm excitation, the NaYF_4: 15 % Yb~(3+), 2 % Er~(3+), x % TiO_2 (x = 0, 1, 5, 7, 10) composite shows several emission peaks at 521, 540, and 655 nm. With the increase of doping TiO_2 that the luminescence intensities of both Yb~(3+) and Er~(3+) emission increase firstly, and reach a maximum at 1 mol% TiO_2, and then get suppressed with the further increase of TiO_2 doping. Our results suggest that, for Yb~(3+)-Er~(3+) co-doped NaYF_4 with doping TiO_2, there will be a high potential in application of novel light conversion devices, especially in solar cells.
