摘要

含有过渡金属或 p 块阳离子的氧化钙苷具有热电、光催化和磁性应用的潜力，但这些四元相的合成途径还不完全清楚。这对设计和制备新型功能材料提出了挑战。我们对 La2O2MQ2（M = +2 阳离子；Q = 硫化物、硒化阴离子）系统进行了实验和计算相结合的研究，探索了合成的热力学限制，并强调了通过相互竞争的反应途径形成的相在稳定性方面的微妙平衡。

La2O2MQ2 phases: Stability and synthetic challenges

Oxychalcogenides containing transition metal or p block cations have potential for thermoelectric, photocatalytic and magnetic applications but the synthetic pathways to these quaternary phases are not fully understood. This presents a challenge to the design and preparation of new functional materials. Our combined experimental and computational study of La₂O₂MQ₂ (M = +2 cation; Q = sulfide, selenide anion) systems explores the thermodynamic constraints on synthesis and highlights the subtle balance in stabilities of phases formed via competing reaction pathways.
