| 摘要: 采用新型水热-微波法合成了纳米晶长余辉发光材料Y2O2S∶Eu3+，Mg，Ti。通过XRD、TEM、荧光光谱对其进行表征。X射线衍射测试表明所制备的Y2O2S∶Eu3+，Mg，Ti纳米发光材料为单相，六方晶。透射电子显微镜(TEM)测试表明所制备的Y2O2S∶Eu3+，Mg，Ti纳米发光材料粒径小，分布集中。激发和发射光谱测试表明Eu3+离子能有效地掺入硫氧化钇基质中，并具有良好的发光性能。余辉光谱测试表明其余辉颜色为红色，具有良好的余辉效果。 |

| Abstract: Long-lasting phosphorescent materials, nanocrystals Y2O2S∶Eu3+,Mg,Ti, were prepared by hydrothermal-microwave method. The results of XRD indicated that the nanocrystals Y2O2S∶Eu3+,Mg,Ti possessed pure phase, hexagonal crystal structure. The results of TEM revealed that the single phase Y2O2S∶Eu3+,Mg,Ti had small size with narrow distribution. Excitation and Emission spectra showed that Eu3+ could be incorporated into yttrium oxysulfides effectively, and had good luminescent properties. The afterglow spectrum indicated that nanocrystals Y2O2S∶Eu3+,Mg,Ti had red afterglow color and good afterglow effect. |
