摘要:
采用传统的高温固相法制备出了不同掺杂浓度的Gd 1-x Tb xNbO4绿色荧光粉。荧光光谱分析表明,Gd 1-x Tb xNbO4荧光粉的最强发射峰归属于Tb 3+离子5D4 → 7F5电子跃迁(543 nm)的强绿光发射且当Tb 3+掺杂浓度为20%时荧光粉的发光强度达到最大值,即绿色荧光粉Gd 1-x Tb xNbO4的最佳掺杂浓度为20%。在最佳掺杂浓度的基础上,于制备过程中添加助熔剂可以进一步提高Gd 1-x Tb xNbO4荧光粉的发光性能,尤其是以Na 2SO 4为助熔剂不仅可以得到分散性好、颗粒尺寸分布范围窄的微米尺寸鹅卵石状颗粒,且位于543 nm处的绿光发射强度相比无任何助熔剂辅助时所得产物的发光强度提高了约1.3倍。
