| 摘 要： | 在Rb2CO3-Li2CO3-Gd2O3-H3BO3体系中,用自发结晶的方法获得了一种钆硼酸盐Rb2LiGdB2O6(RLGBO)单晶,同时,用固相合成法获得了RLGBO粉末多晶。单晶结构解析表明,RLGBO属于正交晶系,Pbcm空间群,晶胞参数a=7.0259(3)A,b=9.6103(4)A,c=10.0562(4)A和z=4。热学性质表明,RLGBO在840℃下保持良好的热稳定性。在RLGBO中分别掺杂2%的Ce3+,80%的Eu3+和50%的Tb3+之后,其结构不会发生改变。在紫外光及近紫外光激发下,RLGBO∶Ce3+,RLGBO∶Eu3+和RLGBO∶Tb3+可分别发射蓝光,红光和绿光。结果表明,RLGBO化合物可作为发光物质的基质材料。

| Abstract: | The gadolinium-based borate Rb2LiGdB2O6(RLGBO)single crystals were obtained by the spontaneous crystallization method from the Rb2CO3-Li2CO3-Gd2O3-H3BO3 system.Meanwhile,the polycrystalline powder RLGBO were obtained by solid phase reaction.The analysis of single crystal structure shows that RLGBO belongs to the orthorhombic system,Pbcm space group,with cell parameters of a=7.0259(3)A,b=9.6103(4)A,c=10.0562(4)A and z=4.Thermal properties indicate that RLGBO is stable below 840℃.After 2%Ce3+,80%Eu3+and 50%Tb3+are doped in the RLGBO respectively,the host structure remains unchange.Under ultraviolet(UV)or near-UV light excitation,RLGBO∶Ce3+,RLGBO∶Eu3+and RLGBO∶Tb3+can emit blue,red and green lights,respectively.The results show that RLGBO is a promising matrix compound for luminescence materials. |
