مستخلص: The rare earth metal, samarium (Sm 3+ ) doped bismuth tungstate (Bi 2 WO 6 ) nanoparticles were prepared by a one-pot hydrothermal method. The powder X-ray diffraction (XRD) analysis confirmed the formation of Bi 2 WO 6 with an orthorhombic crystal structure. The crystallite size of Bi 2 WO 6 decreased from 20.73 to 9.25 nm as the Sm substitution in the W lattice increased. The vibrational modes of W-O, Bi-O, and Sm-O were identified in the range of 500-900 cm -1 . The optical bandgap of Sm 3+ doped Bi 2 WO 6 nanoparticles increased from 2.86 to 2.95 eV with higher Sm doping levels. The surface morphology revealed the formation of flower-like sheets in the Sm 3+ doped bismuth tungstate. The energy dispersive X-ray (EDX) spectrum of Sm 3+ doped Bi 2 WO 6 nanoparticles confirmed the presence of Sm, Bi, W, and O without any other impurities. The small peak detected at 1082.14 eV in the survey scan of Sm 3+ doped Bi 2 WO 6 nanoparticles belonged to Sm3d. In the photocatalytic degradation of direct blue 15 (DB15) under visible light irradiation, the efficiency of the nanoparticles increased with higher Sm 3+ concentration. The obtained results demonstrated that the Sm-Bi 2 WO 6 nanosheets could provide an effective and sustainable solution for treating the wastewater containing direct blue 15 dye.
