稀土发光材料的水热法合成及其发光强度

Rare-earth luminescent materials prepared by hydrothermal method and their luminous intensity

摘要: 采用水热合成法成功制备出了掺铕CaF₂、SrF₂和BaF₂, 并探究了同浓度稀土离子掺杂的CaF₂、SrF₂和BaF₂的发光能力的强弱，得出同浓度稀土离子掺杂的CaF₂、SrF₂和BaF₂中CaF₂的发光能力最强.此外，还通过荧光光度计对不同浓度的CaF₂的发光强度进行了探究，发现随掺杂稀土离子浓度的增加，掺铕CaF₂的发光强度增强.

Abstract: Eu³⁺ doped CaF₂, SrF₂ and BaF₂ have been prepared by hydrothermal method successfully, which is presented in this paper. Rare-earth doped CaF₂, SrF₂ and BaF₂, whose luminous ability is the strongest, have been explored when their concentration is the same. It concludes that the luminous ability of Eu³⁺ doped CaF₂ is the strongest of them. Besides, luminous intensity of Eu³⁺ doped CaF₂ in different concentration has been explored with fluorometer. The result is that luminous intensity of Eu³⁺ doped CaF₂ becomes stronger with the increasing of its concentration.
