摘要

Sm³⁺ doped KSr₂Nb₅O₁₅ (KSN-Sm) ceramics exhibiting the electro-photoluminescent coupling effect were prepared by two-step sintering technology. The microstructures, electrical and luminescent properties were characterized. In addition, the luminescence modulation behavior upon the application of an in-situ electric field was investigated. It was found that the luminescent emission intensity decreased with increasing in-situ dc bias, and a high modulation ratio of approximately 20%@20 kV/cm was achieved. This work demonstrates that KSN-based ferroelectric ceramics with the tetragonal tungsten bronze structure are promising optical materials with good luminescence modulation behavior.
