摘要/Abstract

摘要： 采用高温固相法制备了一系列Sr₃Y_2-xTeO₉∶xEu³⁺新型红色荧光粉,研究了Sr₃Y_2-xTeO₉∶xEu³⁺的物相结构、发光性能、衰减寿命以及热稳定性。研究结果表明新型红色荧光粉Sr₃Y_2-xTeO₉∶xEu³⁺能在近紫外光或蓝光激发下发出强烈的红光,并确定了Sr₃Y_2-xTeO₉∶xEu³⁺的浓度猝灭机制是电偶极-电偶极之间相互作用。其色坐标结果表明,随着掺杂浓度的增加该荧光粉的色坐标均在红色区域。温度相关荧光发射光谱揭示了该荧光粉具有良好的热稳定性。荧光衰减曲线显示在Sr₃Y_2-xTeO₉∶xEu³⁺荧光粉中当x=0.34时为最佳掺杂浓度,其平均荧光寿命为0.619 ms。综合以上研究结果表明新型红色荧光粉Sr₃Y_2-xTeO₉∶xEu³⁺在荧光转换近紫外激发白光二极管中具有良好的应用前景。

Abstract: A series of new red-emitting Sr₃Y_2-xTeO₉∶xEu³⁺ phosphors were prepared by high temperature solid-state method, and the phase structure, luminescent performances, decay life and thermal stability of Sr₃Y_2-xTeO₉∶xEu³⁺ were studied. The results show that new red-emitting Sr₃Y_2-xTeO₉∶xEu³⁺ phosphors can emit intensive red light under near-ultraviolet or blue light excitation, and it demonstrate that the concentration quenching mechanism is attributed to the dipole-dipole interaction between Eu³⁺ ions. The color coordinates of these phosphors with different Eu³⁺ concentrations are in the red spectral region. The temperature-dependent luminescences emission spectra reveal that these phosphors show good thermal stability. The optimal doping concentration of Eu³⁺ is x=0.34 for Sr₃Y_2-xTeO₉∶xEu³⁺ phosphor, and its fluorescence decay lifetime is deduced to be 0.619 ms. These overall results show that new red-emitting Sr₃Y_2-xTeO₉∶xEu³⁺ is promising phosphor applied in phosphor-converted near UV-excited white light-emitting diodes.
