中文摘要 | we reported, for the first time to the best of our knowledge, the sm3+ -doped yttriurn oxysulfide phosphors has reddish orange long-lasting phosphorescence. the phosphor show prominent luminescence in reddish orange due to the electronic transitions of (4)g(5/2) --> h-6(j) (j = 5/2, 7/2, 9/2), the afterglow color of this type of phosphors is a mixture of the three above mentioned electronic transition emissions and have a little different when the concentration of the sm3+ dopant changes. synthesis procedure of the sm3+-yttrium oxysulfide reddish orange phosphor through the flux fusion method with binary flux compositions was presented. the synthesized phosphors were analyzed using x-ray diffraction (xrd) to interpret the structural characterization. the xrd analysis result reveal that the y2o2s:sm3+ phosphor synthesized with a binary flux composition containing (s and na2co3 at a ratio of 1: 1 at 30 wt.% of total raw material) at 1050degreesc for 3 h was in single-phase. luminescence properties of the y2o2s:sm3+ long-lasting phosphor was analyzed by measuring the excitation spectra, emission spectra and afterglow decay curve. the mechanism of the strong afterglow from y2o2s:sm3+ was also discussed in this paper. |
