A series of polycrystalline barium-lead tungstate Ba1-xPbxWO₄ with 0 ≤ x ≤ 1 was synthesized using a classical solid-state method with thermal treatment at 1000 °C. These materials were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier Transform Raman (FT-Raman) spectroscopy. X-ray diffraction profile analyses were performed using Rietveld method. These materials crystallized in the scheelite tetragonal structure and behaved as quasi ideal solid solution. Raman spectroscopy confirmed the formation of the solid solution. Structural distortions were evidenced in X-ray diffraction profiles and in vibration Raman spectra. The scanning electron microscopy experiments showed large and rounded irregular grains. Luminescence experiments were performed under X-ray excitation. The luminescence emission profiles have been interpreted in terms of four Gaussian components, with a major contribution of blue emission. The integrated intensity of luminescence reached a maximum value in the composition range x = 0.3–0.6, in relation with distortions of crystal lattice.

采用经典的固态方法，在1000的热处理温度下，合成了一系列0≤x≤1的多晶钡铅钨酸钡Ba1-xPbxWO ₄。 ℃。这些材料通过X射线衍射（XRD），扫描电子显微镜（SEM），傅立叶变换拉曼（FT-Raman）光谱进行了表征。使用Rietveld方法进行X射线衍射轮廓分析。这些材料以白钨矿四方结构结晶，表现为近似理想的固溶体。拉曼光谱证实了固溶体的形成。在X射线衍射图和振动拉曼光谱中证实了结构变形。扫描电子显微镜实验显示大而圆形的不规则晶粒。发光实验是在X射线激发下进行的。已经用四个高斯分量解释了发光发射曲线，其中蓝色发射起了主要作用。
