通过溶胶-凝胶法制备了纯相的Na,2,WO,4,∶Sb,3+,荧光粉,通过X射线衍射表征了其晶体结构, 使用紫外-可见分光光度计研究了样品的发光性质。结果表明,用250~320 nm范围的紫外光激发时, Na,2,WO,4,∶Sb,3+,荧光粉可在410~550 nm范围内给出较强的光发射。其最佳激发波长为280 nm, 最强发射峰在470 nm处。Na,2,WO,4,∶Sb,3+,荧光粉的最佳制备温度为800 ℃, Sb,3+,的最佳掺杂摩尔分数为0.01。对Na,2,WO,4,∶Sb,3+,荧光粉的发光机理也进行了初步探究。
Na,2,WO,4,∶Sb,3+, phosphors were prepared with a sol-gel method. The samples were characterized with X-ray diffraction, reflectance spectra, emission and excitation spectra. The phosphor can be excited with ultrovilet light in the range of 250~320 nm and give intensitive emission in the range of 410~550 nm. The maximum emission and excitation wavelength is 470 nm and 280 nm, respectively. The optimized sintered temperature is 800 ℃ and samples with a Sb,3+, concentration of 0.01 give the strongest emission. The luminescence mechanism of Na,2,WO,4,∶Sb,3+, phosphors were also briefly discussed.
