N2 - Perovskite-structured Dy-doped BZT–BCNT system has been investigated with variation of Dy doping through the solid-state reaction method. X-ray diffraction (XRD) and microscopic studies confirm the results in the rhombohedral stoichiometry without any secondary phases and uniform grain growth, respectively. Tolerance factor and electronegativity also confirm the presence of Dy doping in BZT–BCNT ceramic system with a stable rhombohedral crystallinity forming vacancy sites for oxygen ions. Optimum piezoelectric (PE) properties in non-Pb PE ceramic systems obtained due to trivalent donor Dy doping at A-site and pentavalent donor Nb at B-site are possible members for actuator and energy harvesters. Dielectric and PE studies signifying the rhombohedral perovskite behavior of this lead-free ceramic system confess that the proposed investigation could yield further potential PE sensors and actuator applicative futuristic studies.
