Strong photoluminescence and high piezoelectric properties of Eu-doped (Ba0.99Ca0.01)(Ti0.98Zr0.02)O3 ceramics

Bifunctional europium doped SrTiO3 ceramics with energy storage and photoluminescence

“…In this regard, the doping of rare-earth ions could improve energy storage properties and meanwhile endow luminescent properties to SrTiO 3 . In addition, it has been reported that proper doping of Eu 3+ can suppress grain growth due to its relatively low diffusion coefficient, which may help improve the dielectric strength of the matrix [4,21]. Nevertheless, so far Eu 3+ doping effect of dielectric storage performance of SrTiO 3 has not been reported.…”

Evaluation of the microstructure, optical properties and hopping conduction mechanism of rare earth doped Ba0.85Ca0.12RE0.03Ti0.90Zr0.04Nb0.042O3 ceramics (RE = Ce3+ and Pr3+)

“…This material was found to be particularly suitable for energy harvesting applications, with an exceptional figure of merit. 13 Moreover, R. Hayati et al reported that the Ce 3+ -modified lead-free BCTZ compound exhibited enhanced electromechanical, piezoelectric and ferroelectric process at room temperature. 14 Finally, I. Zouari et al also reported that improved piezoelectric, dielectric, electro-caloric and ferroelectric process of BT-based compound have been achieved via the incorporation of (RE 3+ , Nb 5+ ) for Ti 4+ in B site and Ca 2+ for Ba 2+ in A site.…”
