摘要

利用高温固相法合成了稀土离子Eu2+, Dy3+掺杂的Ca5MgSi3O12长余辉发光材料. 利用光谱学证明了在材料内部存在与氧空位有关的缺陷发光. 通过对比不同条件下合成样品的发光及余辉性能, 发现氧空位对材料的发光及余辉均起到促进作用. 同时发现氧空位发光可以向发光中心传递能量. 利用热释光曲线系统的分析了氧空位对余辉性能的影响. Ca5MgSi3O12:Eu2+,Dy3+是一种潜在的长余辉发光材料.

Abstract

Ca5MgSi3O12:Eu2+, Dy3+ was synthesized by solid-state reaction. The luminescence center related to the oxygen vacancies existed in the host matrix. Comparing the fluorescence and phosphorescence properties of samples synthesized under different air condiction, we find that the oxygen vacancies played an important role in the fluorescence and phosphorescence properties. Oxygen vacancies can transfer its energy to the luminescence center. Thermoluminescence spectra were used to characterize the effect of oxygen vacancies on the phosphorescence properties. Ca5MgSi3O12:Eu2+,Dy3+ has a great potential to become a promising candidate to be used as long-lasting phosphors.
