Influence of vacuum pre-sintering temperature on the Eu2+–Dy3+ co-doped SrAl2O4 ceramics with persistent luminescence
(Sr0.97Eu0.01Dy0.02)Al2O4 persistent luminescence (PersL) ceramics were fabricated by solid-state reactive pre-sintering in vacuum combined with hot isostatic pressing (HIP) post-treatment adding H3BO3 as a sintering additive. The influence of pre-sintering temperature on the phase composition, microstructure, and PersL performance of (Sr0.97Eu0.01Dy0.02)Al2O4 ceramics was investigated. The results showed that optimum persistent performance was obtained by the ceramics prepared by vacuum pre-sintered at 1600°C for 3 h and HIP post-treated at 1400°C for 3 h under 200 MPa in Ar. The persistent initial luminescence intensity exceeded 9200 mcd/m2 after 5 min when the optimum sample was simulated by the daylight irradiation of 1000 lx, and the persistent emission decay time was longer than 14 h. The trap depth was calculated using two methods, and the results showed that the ceramics prepared at pre-sintering temperature of 1600°C had the highest trap depth.
期刊介绍：
The Journal of the American Ceramic Society contains records of original research that provide insight into or describe the science of ceramic and glass materials and composites based on ceramics and glasses. These papers include reports on discovery, characterization, and analysis of new inorganic, non-metallic materials; synthesis methods; phase relationships; processing approaches; microstructure-property relationships; and functionalities. Of great interest are works that support understanding founded on fundamental principles using experimental, theoretical, or computational methods or combinations of those approaches. All the published papers must be of enduring value and relevant to the science of ceramics and glasses or composites based on those materials.
Papers on fundamental ceramic and glass science are welcome including those in the following areas:
Enabling materials for grand challenges[...]
Materials design, selection, synthesis and processing methods[...]
Characterization of compositions, structures, defects, and properties along with new methods [...]
Mechanisms, Theory, Modeling, and Simulation[...]
JACerS accepts submissions of full-length Articles reporting original research, in-depth Feature Articles, Reviews of the state-of-the-art with compelling analysis, and Rapid Communications which are short papers with sufficient novelty or impact to justify swift publication.
