摘要:
以单分散三聚氰胺-甲醛微球为模板,通过煅烧除去模板,制备出粒径均一的铕掺杂氧化钇空心微球荧光材料. 利用扫描电子显微镜、透射电子显微镜、傅立叶变换红外光谱仪、X射线衍射仪、荧光分度计对氧化物空心微球荧光材料进行表征. 结果表明:成功地制备了铕掺杂氧化钇单分散空心微球,铕元素掺杂进入氧化钇晶体后对氧化钇晶型没有影响,随着铕元素含量的增加,晶格常数逐渐增大. 铕掺杂氧化钇空心球在613 nm处均表现出强烈的发射峰,当铕元素掺杂量为原分子数x=5%时,荧光强度最强;随着铕元素含量的增多,电荷迁移带红移,表明铕-氧键共价性逐渐减弱、离子性逐渐增强.
Abstract:
The hollow microspheres of uniform Europium-doped Yttria(Y2O3∶Eu3+)with different Eu3+ contentswere prepared by a subsequent calcination process using monodispersed melamine-formaldehyde microspheresas templates. The scanning electron microscope,transmission electron microscopy,Fourier transform infraredspectroscopy,X-ray diffractometer and photoluminescence spectrophotometer were employed to characterize thehollow microspheres. The results indicate that the monodispersed Y2O3∶Eu3 + hollow microspheres were preparedsuccessfully,in which the europium doping in the lattice of yttrium oxide has no effect on the crystal phase,andthe cell parameter increases with the Eu3 + contents increasing. Y2O3∶Eu3 + hollow microspheres show a strongemission peak at 613 nm,and the fluorescence intensity of it is the strongest when Eu3+ concentration is 5 at%.The Charge Transfer Band position shows a red shift with the Eu3+ contents increasing,suggesting an increase incovalency or a decreases in iconicity.
