“…These values are comparable to the energy density of doped PbZrO 3 thin films which are known for offering high‐energy density . It is to be mentioned that the obtained values of W ED for BCZT thin films are much higher than that of the BCZT bulk ceramics (0.59 J/cm 3 ) …”

“…The shaded area in Figure C corresponds to the recoverable energy density for BCZT 700 film. Earlier reports suggest that recoverable energy density of antiferroelectric ceramics (≤2.75 J/cm 3 ) and ferroelectric ceramics (0.59 J/cm 3 ) are very low. However, with the advent of modern thin film technology it was confirmed that very high‐energy density could be achieved from ferroelectric thin films.…”

Lead‐free piezoelectric Ba0.85Ca0.15Ti0.90Zr0.10O3 (BCZT) thin films were fabricated on Si/SiO2/TiO2/Pt (100) substrates following chemical solution deposition technique. Microstructure of the nano‐sized BCZT particles crystallized in the thin film was thoroughly characterized. Ferroelectric, dielectric and piezoelectric properties of the films were investigated in detail. The BCZT films annealed at 800°C temperature exhibited high remanent polarization of 25 ± 1 μC/cm2, energy density of 17 J/cm3, dielectric constant of 1550 ± 50 and dielectric tunability of 50%. Converse piezoelectric coefficients (d33) obtained from piezo‐response force microscopy (PFM) measurements on BCZT grains of different grain size (20‐100 nm) distributed on the BCZT 700 film varied widely from 90 to 230 pm/V. The same for BCZT 800 measured on different grain size (30‐130 nm) varied from 120 to 295 pm/V. These BCZT thin films with high dielectric, ferroelectric, and piezoelectric properties might be good alternative to the PZT films for thin film piezoelectric device applications.

Ba 0.85 Ca 0.15 Zr 0.10 Ti 0.90 O 3 (BCZT) lead-free ceramics demonstrated excellent dielectric, ferroelectric, and piezoelectric properties at the morphotropic phase boundary (MPB). So far, to study the effect of morphological changes on dielectric and ferroelectric properties in lead-free BCZT ceramics, researchers have mostly focused on the influence of spherical grain shape change. In this study, BCZT ceramics with rod-like grains and aspect ratio of about 10 were synthesized by surfactant-assisted solvothermal route. X-ray diffraction (XRD) and selected area electron diffraction (SAED) performed at room temperature confirm the crystallization of pure perovskite with tetragonal symmetry. Scanning electron microscopy (SEM) image showed that BCZT ceramics have kept the 1D rod-like grains with an average aspect ratio of about 4. Rod-like BCZT ceramics exhibit enhanced dielectric ferroelectric (ε r = 11,906, tanδ = 0.014, P r = 6.01 µC/cm², and E c = 2.46 kV/cm), and electrocaloric properties (ΔT = 0.492 K and  = 0.289 (Kmm)/kV at 17 kV/cm) with respect to spherical BCZT ceramics. Therefore, rod-like BCZT lead-free ceramics have good potential to be used in solid-state refrigeration technology.

“…Based on previous studies, there had been many reports about the energy-storage properties of ceramics, such as Bi-based lead-free piezo-ceramics, Pb(Mg 1/3 Nb 2/3 )O 3 -PbTiO 3 , (Bi 0.5 Na 0.5 )TiO 3 -Ba 0.85 Ca 0.15 Ti 0.9 Zr 0.1 O 3 , Ba 0.95 Ca 0.05 Zr 0.3 Ti 0.7 O 3 , etc. [17,18,19,20]. However, the recoverable energy-storage density of previous works is lower than the AFE materials for energy storage ceramic capacitors application.…”

(Pb 0.97 La 0.02 )(Zr 0.95 Ti 0.05 )O 3 (PLZT2/95/5) ceramics were successfully prepared via a solid-state reaction route. The dielectric properties were investigated in the temperature region of 26-650 • C. The dielectric diffuse anomaly in the dielectric relaxation was found in the high temperature region of 600-650 • C with increasing the measuring frequency, which was related to the dynamic thermal process of ionized oxygen vacancies generated in the high temperature. Two phase transition points were detected during heating, which were found to coexist from
