%X We reported a sandwich structured Pb(Zr 0.4Ti 0.6)O 3/BaZr 0.2T i0.8O 3/Pb(Zr 0.4Ti 0.6)O 3 (PZT/BZT/PZT) film fabricated by using the sol¨Cgel method, which was dense and uniform with a unique perovskite structure. The PZT/BZT/PZT films displayed high dielectric constants up to 1722.45 at the frequency of 10 kHz. Additionally, the enhanced energy storage density of 39.27 J¡¤cm £¿3 was achieved at room temperature and 2.00 MV/cm, which was higher than that of the individual BaZr 0.2T i0.8O 3 film (21.28 J¡¤cm £¿3). Furthermore, the energy storage density and efficiency of PZT/BZT/PZT film increased slightly with the increasing temperature from £¿140 ¡ãC to 200 ¡ãC. This work proves the feasibility and effectiveness of a sandwich structure in improving dielectric, leakage, and energy storage performances, providing a new paradigm for high-energy¨Cdensity dielectrics applications.
