Abstract
An effective route to regulate up-conversion luminescence (UCL) and polarization properties has been developed in tetragonal tungsten bronze ferroelectrics (TTBs). In this work, we have synthesized a series of (Sr0.29Er0.01)Ba0.7Nb2−xMoxO6 (SBN-Ax, 0 ≤ x ≤ 0.1) and Sr0.3Ba0.7(Nb1.99−xMoxEr0.01)O6 (SBN-Bx, 0 ≤ x ≤ 0.1) ceramics. Through investigating the UCL spectra of SBN-Ax and SBN-Bx ceramics, markedly different enhancement effects of UCL intensity have been revealed which can be attributed to the peculiar structural feature of TTBs. Furthermore, temperature sensing, dielectric and ferroelectric properties have also confirmed to display B-site substitution-dependent intriguing behaviors.
