Abstract The near‐infrared luminescence properties of Pr 3+ /Yb 3+ : PLZT ferroelectric ceramics have been examined for the first time. Independently, upon either 450 nm (Pr 3+ ) or 980 nm (Yb 3+ ) excitation, luminescence centered at 1340 nm was observed, which corresponds to the 1 G 4 → 3 H 5 transition of Pr 3+ . Several spectroscopic parameters for the 1 G 4 → 3 H 5 transition of Pr 3+ ions were determined. The average product of emission cross section and radiative lifetime were relatively large for all x /65/35 PLZT samples ( x =6‐10) studied, with values close to 105±2 (×10 −26 cm 2 ·s). These spectroscopic investigations indicate that Pr 3+ /Yb 3+ : PLZT ferroelectric ceramics are promising candidate for efficient sources emitting near‐infrared radiation at 1340 nm.
