“…In addition to the above-mentioned materials, they have many useful applications in different fields because of their various properties (solid-state lasers, dielectric materials, and phosphors). 15), 16) Understanding the potential of these materials, crystal structure analyses of LaTiNbO 6 (where La represents Lanthanide rare earth materials) have confirmed an aeschynite type with the space group Pmna for elements like Sm, La, Pr, Ce, Nd, and Eu, while euxenite structure type compounds are identified containing space group Pbcn for Dy, Gd, Tb, Ho, Tm, Er, and Yb. 17) So, there is a great probability of obtaining a solid solution with euxenite structure by substituting Lanthanum series trivalent ions (earth materials Tb, Dy) in the niobate structure.…”

This present study focuses on the synthesis and characterization of orthorhombic niobate compounds, including TbNbTiO 6 and DyNbTiO 6 , as well as their solid solutions. These solid solutions were synthesized by substituting Dy 3+ for Tb 3+ in a high-temperature solid-state reaction, while maintaining a stoichiometric atomic ratio. The study has identified the solid solution range as well. X-ray diffraction (XRD) analyses of all synthesized compounds revealed that their crystal structures exhibit an orthorhombic system within the Pbcn space group. Additionally, scanning electron microscopy (SEM) was employed for surface morphology assessments, and UVvisible diffused reflectance spectroscopy (DRS) was used for band gap assessments. Furthermore, electronic properties, such as the band structure and density of states, were computationally elucidated. The study also delved into the photocatalytic properties of the materials.
