摘要：以氟化钇(YF_3)为基质材料,采用共沉淀法合成了YF_3:Yb^(3+)/Er^(3+)/Tm^(3+)上转换发光材料。采用X射线衍射仪(XRD)、热重差热分析仪(DTA)和荧光光谱分析对材料的物相结构、烧结温度和发光性质进行了研究。结果表明,掺入稀土离子没有改变YF3晶体结构,在980nm近红外波长激发下,出现了多个波段的发光现象,Yb^(3+)、Er^(3+)、Tm^(3+)不同的掺杂量分别对应于材料不同的发光规律。本文还探讨了上转换发光机制,确定了该体系荧光粉的最佳烧结温度。
A series of YF3 ：Yb^3＋/Er^3＋/Tm^3＋ upconversion materials were synthesized via the chemical coprecipitation method based on yttrium fluoride （YF3）. The phase structure, sintering temperature and luminescence properties of the as-prepared products were characterized by XRD,DTA and the fluorescence spectrum analysis . The results showed that the crystal structure of YF3 didn＇t change after tridoping Yb^3＋/Er^3＋/Tm^3＋. The luminescence phenomenon of multiple bands appeared under the 980 nm nearinfrared excitation. Different doping amounts of Yb^3＋ , Er^3＋ , Tm^3＋ correspond to different luminescence laws. The upconversion mechanism was also discussed, and the optimum sintering temperature of the phosphors was determined.
