摘要

摘要: 采用高温固相法制备了一系列Eu³⁺掺杂的Na₂Ca₃Si₆O₁₆红色荧光粉.用X射线粉末衍射仪表征了荧光粉Na₂Ca_3-xSi₆O₁₆:xEu³⁺的结构.研究显示，Eu³⁺的掺入并未使Na₂Ca₃Si₆O₁₆晶体产生杂相.采用荧光分光光度计分析了Na₂Ca_3-xSi₆O₁₆:xEu³⁺ 的光学性质. Na₂Ca_3-xSi₆O₁₆:xEu³⁺荧光粉发红光，其中以波长611 nm的发射峰强度最强. Eu³⁺的掺杂对Na₂Ca_3-xSi₆O₁₆:xEu³⁺荧光粉发射光谱的峰形和峰位置无明显影响，但发光强度与Eu³⁺的掺杂量(摩尔分数)有关，当Eu³⁺的掺杂量为0.08时，Na₂Ca_3-xSi₆O₁₆:xEu³⁺荧光粉的发光强度达到最大值，掺杂量继续增大时会发生浓度淬灭现象，这可能是由多电子偶极相互作用引起的.结果表明：Na₂Ca_2.92Si₆O₁₆:0.08Eu³⁺荧光粉是一种潜在的可用于白光LED的红色发光材料.

Abstract: A series of Na₂Ca_3-xSi₆O₁₆:xEu³⁺ was prepared with high temperature solid-state reaction and structurally characterized with X-ray powder diffraction. The results of X-ray powder diffraction showed that Eu³⁺-doping had no significant effect on the crystal structure of Na₂Ca₃Si₆O₁₆:Eu³⁺. Its optical properties were checked with the spectrofluorometer. The results showed that the Na₂Ca_3-xSi₆O₁₆:xEu³⁺ phosphor emitted red light with the strongest emission peak at 611 nm. The doping of Eu³⁺ did not change the peak shape and position of the emission spectra of Na₂Ca_3-xSi₆O₁₆:xEu³⁺phosphor. However, the doping content (mole fraction) of Eu³⁺ was related to the luminescence intensity. When the concentration of Eu³⁺ was 0.08, the Na₂Ca_3-xSi₆O₁₆:xEu³⁺ showed the strongest luminescence intensity. The concentration quenching was observed when Eu³⁺ concentration was over 0.08, and the concentration quenching mechanism was verified as multipole-multipole interaction. The results indicated that Na₂Ca_2.92Si₆O₁₆:0.08Eu³⁺ phosphor was a potential red light-emitting material for white LED.
