采用溶胶-凝胶法合成了La 2-xW 3 O 12：xTb（0.005 ≤ x ≤ 0.10）荧光粉。采用粉末X射线衍射（PXRD）和傅里叶变换红外光谱（FTIR）技术进行结构表征。通过Scherrer公式估计微晶尺寸，发现其在45 - 56 nm的范围内。在544 nm处监测下记录所有制备的磷光体的激发光谱。在不同激发波长（274、147和172 nm）下记录的发射光谱显示了Tb 3+离子的所有特征发射。因此，所制备的磷光体适合于在等离子体显示面板中应用。
The La2-xW3O12:xTb (0.005 ≤ x ≤ 0.10) phosphors were synthesized by a sol-gel process. The structural characterization was carried out using powder X-ray diffraction (PXRD) and Fourier transform infrared spectra (FTIR) techniques. The crystallite size was estimated by Scherrer formula and it is found to be in the range of 45−56 nm. The excitation spectra for all the prepared phosphors were recorded under monitoring at 544 nm. The emission spectra recorded for different excitation wavelengths (274, 147 and 172 nm) show all the characteristic emissions of Tb3+ions. Thus, the prepared phosphors are suitable for application in plasma display panels.
