Cerium dioxide-based compounds are known as a significant rare earth oxide based- compounds. It has been reported that these oxide materials can display interesting magnetic and catalytic characteristics owing to its particular f-electron configuration [1-3]. In this work, dysprosium cerate nanomaterials were fabricated via a simple eco-friendly method with the aid of the orange extract for the first time, and were characterized by SEM, XRD, EDS, and FT-IR. Figure 1 displays SEM image of as-produced dysprosium cerate nanomaterials.
