Transparent　dielectric　ceramics　with　ultrafast　discharge　rates　and　gigantic　power　densities　are　ideal　candidates　for　transparent　pulse　capacitors　(TPCs).　However,　the　requirement　of　a　high　external　electric　field　and　inferior　temperature　stability　hinder　practical　applications.　(Bi0.5Na0.5)TiO3-based　ceramics　exhibit　large　polarization　and　two　characteristic　dielectric　peaks,　easy　to　obtain　high　energy-storage　density　under　low　electric　fields　(low-E)　and　maintain　stable　energy-storage　performance　(ESP)　within　a　wide　temperature　range.　However,　their　low　optical　transmittance　(T%)　limits　their　development　into　TPCs.　In　this　work,　to　concurrently　obtain　high　T%　and　excellent　ESP　and　stability　under　low-E　conditions,　we　propose　a　collaborative　optimization　strategy　for　determining　the　regulations　of　grain　size,　bandgap　energy　and　domain　structure.　The　results　show　that　the　pellucidity　and　energy-storage　characteristics　improve　with　decreasing　grain　and　domain　sizes.　A　relatively　high　T%　of　45.6　%　(at　710　nm)　and　recoverable　energy-storage　density　(Wrec　∼　3.46　J　cm−3　at　197　kV　cm−1)　are　obtained　for　the　(1-x)[0.85(Bi0.5-3yNa0.5-yYb3yHoyTiO3)-0.15SrZrO3]-xBaHfO3　ceramics.　Additionally,　the　dielectric　temperature　stability　also　results　in　splendid　storage　temperature　stability　(ΔWrec/Wrec　＜　3.1　%　in　the　range　of　0–200　°C).　Importantly,　codoping　Ho/Yb　in　the　ceramics　induces　excellent　fluorescence　temperature　sensing　feature.　The　multifunctional　TPCs　have　application　potential　in　the　field　of　search　and　rescue　signal　transmission,　providing　ideas　for　developing　novel　optoelectronic　devices.　©　2024
