A Multifunctional High-Entropy Perovskite Ceramics with Enhanced Energy Storage and Photoluminescence Properties
High-entropy perovskite ceramics have become a topic of interest due to their unique properties and compositional versatility. This study pioneers the development of multifunctional high-entropy perovskite ceramics by incorporating the rare-earth element samarium (Sm) into the (Bi0.4Na0.2K0.2Ba0.2)TiO3 matrix. The introduction of Sm3+ increases the configurational entropy and introduces photoluminescence activation centers. Our results show that (Bi0.4−xSmxNa0.2K0.2Ba0.2)TiO3 ceramics with x ≤ 0.12 retain pure perovskite phase and exhibit enhanced dielectric relaxation properties. The presence of Sm3+ ions disrupts the long-range ferroelectric order, resulting in lower maximum polarization and remanent polarization. In particular, the ceramic sample with x = 0.08 exhibits exceptional energy storage and photoluminescence properties. It achieves a recoverable energy storage density of 1.64 J cm−3 and an efficiency (η) of 79.2% under a low electric field of 180 kV cm−1. These properties position the material as a promising candidate for applications in electro-optical devices.
