Abstract
Abstract Effects of Li- and La-doping on the structural, ferroelectric, and strain properties of Bi 1/2 (Na 0.82 K 0.18 ) 1/2 TiO 3 (BNKT) ceramics were compared. In this study, Li + was selected as the A-site acceptor and La 3+ as the A-site donor. Li doping resulted in hardening of BNKT with an improved mechanical quality factor ( Q m ) of 253 and an increased coercive field ( E c ), while La doping brought about a softening effect that was evidenced by an improved piezoelectric constant ( d 33 ) of 172 pC/N and decreased E c . In addition, the large normalized bipolar strain ( S max / E max ) was obtained up to 650 pm/V in 3 mol% La-doped BNKT.
