Aging-Resistant Behavior and Room Temperature Electron Spin Resonance of Nd(3+) in Singly and Doubly Doped BaTiO(3) Ceramics Associated with Preservation History

The (Ba(0.96)Nd(0.04))Ti(0.99)O(3) (BN4T) and (Ba(0.96)Nd(0.04))(Ti(0.94)Ce(0.05))O(3) (BN4TC5) ceramics were prepared via the mixed oxide route exhibited tetragonal and pseudo-cubic structures, respectively. After they were preserved over a long period of time, a broader electron spin resonance (ES...

description The (Ba(0.96)Nd(0.04))Ti(0.99)O(3) (BN4T) and (Ba(0.96)Nd(0.04))(Ti(0.94)Ce(0.05))O(3) (BN4TC5) ceramics were prepared via the mixed oxide route exhibited tetragonal and pseudo-cubic structures, respectively. After they were preserved over a long period of time, a broader electron spin resonance (ESR) signal at g = 2.338 and a narrow ESR signal at g = 2.151 were detected at room temperature (RT) for BN4T and BN4TC5, respectively. They most likely originated from the Nd(3+) Kramers ions in BN4T and Nd(3+)-Ce(4+) defect complexes in BN4TC5 ceramics, respectively. The origins of these two ESR signals and the aging-resistant dielectric behavior are further discussed.
