Abstract

We developed a paste of praseodymium-doped calcium strontium titanium oxide perovskite phosphor nanoparticles prepared by supercritical hydrothermal synthesis and successfully prepared freestanding films using simple screen printing. In addition, when investigating the luminescence properties of the obtained films and sintered freestanding films, we observed a strong luminescence corresponding to a wavelength of 612 nm. The development of freestanding film phosphors using nanoparticles as raw materials will greatly contribute to the promotion of electroluminescent device development, given that the film thickness can be freely controlled.

超临界水热合成掺pr纳米CaSrTiO3制备独立薄膜

通过超临界水热合成制备了一种掺镨锶钛氧化物钙钛矿荧光粉纳米颗粒浆料，并通过简单的丝网印刷成功制备了独立薄膜。此外，在研究制备的薄膜和烧结的独立薄膜的发光性能时，我们观察到波长为612 nm的强发光。以纳米颗粒为原料的独立薄膜荧光粉的开发将极大地促进电致发光器件的发展，因为薄膜厚度可以自由控制。

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.
