Abstract
En 中文
Transparent dielectric ceramics are indispensable materials for next-generation pulse capacitors and have been widely utilized in advanced optoelectronic integration, smart displays, and pulsed power systems. However, simultaneous achieving of high optical transmittance (T%) and high energy storage remains a significant challenge. In this work, a synergistic strategy integrating grain size regulation with bandgap energy (Eg) engineering is employed, and optimization is realized by incorporating Ba(Sc0.5Nb0.5)O3 into a (Bi0.5Na0.5)TiO3 matrix. Microstructural control effectively enhanced the optical transmittance (T%) of the ceramic, which reached a maximum of 36.47% at x = 0.25. The 0.8BNT-0.2BSN ceramic exhibited the best overall performance, with a T% of 36.1% (at 780 nm) and a recoverable energy density (Wrec) of 3.01 J/cm3 under a low breakdown electric field (Eb) of 230 kV/cm. Furthermore, the material exhibited an ultrafast discharge time (83 ns) and a high power density (PD) of 40.3 MW/cm3. Combining high transparency with pulse performance, this multifunctional material holds significant promise for transparent pulse capacitor applications.
