Samarium vanadate (SmVO₄), a fascinating rare earth metal orthovanadate, has been the focal point in the solar-driven applications due to optimal band positions and a narrow band gap, thereby broadening the absorption capacity within the visible light region.

To fill this gap, the review systematically elucidates the crystallographic, electronic and optical properties, followed by synthesis methods.
