本文研究了在紫外光激发下，Ｃｅ３＋、Ｄｙ３＋共掺杂的ＢａＹＢ９Ｏ１６发射光谱，激发光谱以及发光强度随组成而变化的规律。结果表明，Ｃｅ３＋对Ｄｙ３＋发光有较强的敏化作用，Ｃｅ３＋→Ｄｙ３＋的能量传递效率达９０％以上，能量传递机理为电偶极—电偶极相互作用的共振传递。
In this paper, the emission spectra, excitation spectra and luminescence intensity of BaYB9O16 co-doped with Ce3 + and Dy3 + were studied. The results show that Ce3 + has a strong sensitizing effect on Dy3 + emission and the energy transfer efficiency of Ce3 + → Dy3 + is above 90%. The energy transfer mechanism is the resonance transfer of electric dipole-dipole interaction.
