Kurzbeschreibung (Abstract)
3BaO-3TiO2-B2O3 (BTBO) glass-added ferroelectric Ba0.85Sr0.15Zr0.1Ti0.9O3 (BST-BZT) ceramics were synthesized using a conventional solid state reaction route. BTBO glass settled at grain boundaries which has been confirmed from energy dispersive X-ray spectroscopy (EDX). Such effects were observed to benefit properties like the pyroelectric coefficient from 3.4x10^-4 C/m2K (0% glass) to 4.29x10^-4 C/m2K (2% by wt. glass) at 303 K. The dielectric constant decreased from 2937 to 2514 with 2% glass addition at 303K (1 kHz). However, this reduction in dielectric constant increases the pyroelectric figure of merits (FOMs) for high current responsivity (Fi), voltage responsivity (Fv), detectivity (Fd), energy harvesting (Fe), and (F*e ) by 50%, 126%, 49%, 81%, and 76%, respectively, for 2% glass sample as compared with 0% glass at 303 K. Some of the FOMs even surpass the reported FOMs of well-known pyroelectric ceramics. Published by AIP Publishing.
