Investigation of Piezoelectric and Photoluminescence Properties of the Multifunctional La2sn2o7 and Ho2sn2o7 Pyrochlore Smart Materials Doped With Eu3+

Abstract

RE2-xEuxSn2O7 (RE:La3+ and Ho3+, x:0.10) materials were synthesized having both pholuminescence and piezoelectric properties using with solid state reaction method at various reaction temperature and heating duration in open atmosphere. The thermal behaviors, crystal system, surface morphology, EDX analysis, Curie tempereture, photoluminescent properties, dielectric and piezoelectric properties of Eu3+ ions doped La2Sn2O7 and Ho2Sn2O7 were investigated. Both multi-functional smart materials show dielectric, piezoelectric properties and photoluminescence properties which is responsible transitions of doping Eu3+ ions.
