| 摘要: 以单分散的碳球为硬模板，采用均匀共沉淀法合成了Y2O2S∶Eu3+空心微球。通过XRD、SEM、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+空心微球为单相，六方晶。扫描电子显微镜(SEM)和透射电子显微镜(TEM)测试表明所制备的Y2O2S∶Eu3+空心微球粒径小，分布均匀。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。 | |

| Abstract: Red-emitting phosphors Y2O2S∶Eu3+ hollow microspheres were synthesized by monodisperse carbon spheres as hard templates through homogeneous precipitation technique. The products were characterized by the X-ray diffraction (XRD) patterns, scanning electron microscopy (SEM) images, transmission electron microscopy (TEM) images and photoluminescence (PL) spectra. The results of XRD indicated that the Y2O2S∶Eu3+ possessed pure phase, hexagonal crystal structure. The results of SEM and TEM revealed that the single phase Y2O2S∶Eu3+ hollow microspheres had small size and uniform distribution. Excitation and Emission spectrum showed that Eu3+ could be incorporated into yttrium oxysulfides effectively and have good luminescent properties. | |
