A series of Pr 6 O 11 ( x = 0–0.70 mol%)‐doped TiO 2 ceramics were synthesized by the conventional solid‐state reaction method. The microstructure, electrical, and luminescence properties were systematically investigated. The results showed that the as‐prepared TiO 2 ceramics exhibited strong red emission at 606 nm at room temperature and the optimal photoluminescence were obtained at x = 0.30. In addition, the nonlinear coefficient was improved with the amount of Pr 6 O 11 dopant, reaching the maximum value at x = 0.50. Therefore, Pr 6 O 11 ‐doped TiO 2 ceramics, which simultaneously exhibited luminescent properties and good electrical properties, would be useful in novel multifunctional devices.
