| description | Rare earth element-doped Bi<sub>0.5</sub>Na<sub>0.5</sub>TiO<sub>3</sub>–BaTiO<sub>3</sub> (BNT–BT–RE) polycrystalline thin films were processed on a platinized substrate by chemical solution deposition. The microstructure, dielectric, and ferroelectric properties were investigated for all prepared films. It was found that the incorporation of rare earth elements into the BNT–BT matrix increases both the dielectric constant and the breakdown strength while maintaining low dielectric losses, leading to an enhancement of the energy storage density to <i>W<sub>rec</sub></i> = 12 and 16 J/cm<sup>3</sup> under an effective field of <i>E</i> = 2500 kV/cm, for Nd- and Dy-based films, respectively. The optical properties of films containing the lanthanide element were investigated and the obtained results bear interest for luminescence applications. The simultaneous appearance of ferroelectric and optical properties in the system under investigation is very promising for advanced optoelectronic devices. |
