Abstract The burgeoning requirement for compact electronic devices has intensified research into lead‐free dielectric ceramics that offer superior recoverable energy storage density and efficiency at low electric fields. In this study, we report the synthesis of Nd 3+ ‐doped (Bi 0.4 K 0.2 Na Sr )TiO 3 perovskite via solid‐state reaction technique. synthesized adopted a tetragonal crystal structure. As concentration ions increased, both maximum constant ( ε m ) its corresponding temperature T decrease. incorporation perturbed long‐range ferroelectric order, leading to diminished polarization P remanent r ). achieved optimal properties with 12 mol% doping, showcasing significant 1.50 J/cm field 140 kV/cm, along an exceptional 94.6%. This not only highlights promising candidate materials in applications but also introduces innovative approach enhance performance.
