摘要

采用溶胶—凝胶法制备出了CaSiO₃:Eu³⁺Bi³⁺和Sr₂SiO₄:Eu³⁺Bi³⁺，对比分析了两者的激发光谱与发射光谱，探讨了基质改变对Eu³⁺、Bi³⁺发光性能的影响。结果表明Sr₂SiO₄:Eu³⁺Bi³⁺中Bi³⁺—Eu³⁺之间的能量传递效率明显高于CaSiO₃:Eu³⁺Bi³⁺中的。

Abstract:

CaSiO₃:Eu³⁺Bi³⁺and Sr₂SiO₄:Eu³⁺Bi³⁺ were prepared by means of Sol-Gel method .The influences of host materal change on Eu³⁺and Bi³⁺were researched by contrasting the excitation and emission spectras of CaSiO₃:Eu³⁺Bi³⁺ and Sr₂SiO₄:Eu³⁺Bi³⁺. The results showed that energy transfer efficiency between Bi³⁺and Eu³⁺ in Sr₂SiO₄:Eu³⁺Bi³⁺was obviously higher than the one which was in CaSiO₃:Eu³⁺Bi³⁺.

Key words: CaSiO₃:Eu³⁺Bi³⁺ Sr₂SiO₄:Eu³⁺Bi³⁺
