| 摘 要： | 采用柠檬酸钠为表面活性剂的水热法制备了NaGd(MoO4)2∶xEu3+(x=10%, 20%, 30%, 40%)和NaGd(MoO4)2∶7%Eu3+, ySO2-4/BO3-3荧光粉，对所制备样品的晶相、形貌、发光性质进行了表征。XRD分析表明NaGd(MoO4)2∶xEu3+和NaGd(MoO4)2∶7%Eu3+, ySO2-4/BO3-3荧光粉均为四方相的白钨矿结构；红外光谱测试发现有SO2-4/BO3-3的特征吸收峰，这表明SO2-4/BO3-3被成功掺入基质；荧光光谱测试说明，在NaGd(MoO4)2基质中Eu3+掺杂量为30%时发光最强；通过研究NaGd(MoO4)2∶7%Eu3+, ySO2-4/BO3-3荧光粉的发射光谱，发现适量的SO2-4/BO3-3掺杂会使Eu3+的特征发射增强，且掺杂10%SO2-4或10%BO3-3后可以减少3%左右的Eu3+掺杂，起到了节约稀土掺杂量的作用。 |

| Abstract: | NaGd(MoO4)2∶xEu3+(x=10%, 20%, 30%, 40%) and NaGd(MoO4)2∶7%Eu3+, ySO2-4/BO3-3 phosphors were prepared by hydrothermal method with sodium citrate as a surfactant. The crystal phase, morphology and luminescent properties of the prepared samples were characterized. The results showed that the structures of NaGd(MoO4)2∶xEu3+ and NaGd(MoO4)2∶7% Eu3+, ySO2-4/BO3-3 phosphors were tetragonal scheelite. The characteristic absorption peak of SO2-4/BO3-3 was found by infrared spectroscopy, indicating that SO2-4/BO3-3 was successfully incorporated into the matrix. The emission spectrum of NaGd(MoO4)2∶30%Eu3+ was the strongest. Besides, by studying the emission spectrum of NaGd(MoO4)2∶7%Eu3+, ySO2-4/BO3-3 phosphors, it can find that appropriate doping of SO2-4/BO3-3 can enhance the characteristic emission intensity of Eu3+. The addition of 10% SO2-4 or 10% BO3-3 can reduce the doping of Eu3+ by about 3%, which can save the doping amount of rare earth. |
