| 摘 要： | 以柠檬酸三钠为结合剂,采用水热法结合高温烧结两步法制备了一系列NaY1-x(WO4)2:xSm3+(x=0、0.005、0.010、0.015、0.020、0.025、0.030)粉末。通过X射线衍射(XRD)、扫描电镜(SEM)、红外光谱(FT-IR)和荧光性能(PL)对粉末的相结构、形貌、成分以及发光性能进行了表征。研究结果表明,所合成粉末为NaY(WO4)2的纯相,属四方晶系白钨矿结构,其形貌为3D花形。在405 nm的光激发下,NaY(WO4)2:Sm3+粉末在600 nm处具有最高的荧光强度,对应于Sm3+的4G5/2→6H7/2磁偶极跃迁,观察到橙红光发射,且Sm3+最佳掺杂摩尔分数为0.015时,粉末显示出最强的荧光发射强度。

| Abstract: | A series of self-assembled 3D flower-like NaY1-x(WO4)2∶x Sm3+(x=0,0.005,0.010,0.015,0.020,0.025,0.030)powders were prepared by hydrothermal method and high temperature sintering,with trisodium citrate as the anchoring agent.The phase structure,morphology,composition and luminescence properties were characterized by X-ray powder diffraction(XRD),scanning electron microscopy(SEM),infrared spectrum(FT-IR)and photoluminescence spectroscopy(PL),respectively.The results show that the synthesized samples are pure NaY(WO4)2 with tetragoonal scheelite structure.NaY(WO4)2∶Sm3+powders can be excited by a wavelength of 405 nm and exhibit a strong orange-red emission at 600 nm,corresponding to the 4G5/2→6H7/2 magnetic dipole transition of Sm3+.The optimum doping molar fraction of Sm3+is determined to be of 0.015 based on the maximum intensity of fluorescence emission. |
