doi:10.12052/gdutxb.210008

摘要/Abstract

摘要： 采用高温固相法成功制备了双钙钛矿结构的Sr₂GdSbO₆:Eu³⁺红色荧光粉，并表征了其XRD、光致发光光谱和荧光衰减寿命曲线。Sr₂Gd_0.8SbO₆:0.2Eu³⁺荧光粉的XRD图谱的峰位与标准卡片峰位基本吻合，表明Eu³⁺的掺杂并未改变基质的晶体结构，Rietveld精修后的晶体参数也验证了该结果。样品的激发光谱为紫外光区的一个以340 nm为中心的宽光谱；在340 nm光源的激发下，样品的最强发射是一个中心波长为593 nm的橙红光发射波段。运用Dexter理论分析出样品的浓度淬灭机理为偶极−偶极相互作用。常温下Sr₂Gd_0.8SbO₆:0.2Eu³⁺荧光粉的荧光衰减寿命为4.202 ms，外量子效率为24.8%，升温至150 ℃时其外量子效率仍保持为常温下外量子效率的68.8%。经计算得到Sr₂GdSbO₆:Eu³⁺荧光粉的色纯度最高可达99.5%。将Sr₂Gd_0.8SbO₆:0.2Eu³⁺荧光粉、蓝粉、绿粉以及365 nm的紫外芯片封装制作成的LED器件可以发射出亮眼的白光。这些结果表明Sr₂GdSbO₆:Eu³⁺荧光粉是一种潜在的用于白光LED的红色荧光粉。

Abstract: The Sr₂GdSbO₆:Eu³⁺ red phosphor with double perovskite structure was successfully prepared by high temperature solid phase method and its XRD, photoluminescence spectrum and fluorescence decay lifetime were characterized. The XRD of the Sr₂Gd_0.8SbO₆:0.2Eu³⁺ phosphor is basically consistent with the peak position of the standard card, indicating that the doping of Eu³⁺did not change the crystal structure of the matrix. The crystal parameters after Rietveld refinement also verify the result. The photoemission spectrum shows that the sample has a wide excitation area centered at 340 nm in the ultraviolet region; under the excitation of a 340 nm light source, the strongest emission of the sample is an orange-red emission band with a center wavelength of 593 nm. Using Dexter theory to analyze the concentration quenching mechanism of the sample is the dipole-dipole interaction. The fluorescence decay life of Sr₂Gd_0.8SbO₆:0.2Eu³⁺ phosphors at room temperature is 4.202 ms, and the external quantum efficiency is 24.8%. When the temperature is raised to 150 ℃, the external quantum efficiency remains 68.8% of that at room temperature. The calculated color purity of Sr₂GdSbO₆:Eu³⁺ phosphor can reach 99.5%. Sr₂Gd_0.8SbO₆:0.2Eu³⁺ phosphor, blue phosphor, green phosphor and 365 nm UV chip package were made into LED devices which can emit bright white light. These results indicate that Sr₂GdSbO₆:Eu³⁺ phosphor is a potential red phosphor for white LED.
