Herein we report on the broad-band direct white-light originating from a single component emitter, namely a novel three-periodic metal-organic framework (MOF). This material features an unprecedented topology with (3,4)-connected nodes. The structure-function relationship in this system is driven by two complementary unique structural features: corrugation and interpenetration. Good correlation between simulated and experimental emission spectra has been attained, resulting in optimized color properties that approach requirements for solid-state lighting (SSL). Guided by the optimized calculated spectra, the tunability of the assembly was proven by the successful in-framework co-doping of Eu(3+). This resulted in significantly improved color properties, opening new paths for the rational design of alternative materials for SSL applications.
在此,我们报告了源自单个组件发射器的宽带直接白光,即一种新型的三周期金属有机骨架(MOF)。该材料具有前所未有的拓扑结构,具有(3,4)连接的节点。该系统中的结构-功能关系由两个互补的独特结构特征驱动:波纹和互穿。已实现模拟和实验发射光谱之间的良好相关性,从而优化了接近固态照明(SSL)要求的颜色特性。在优化计算光谱的指导下,通过在框架内成功共掺杂 Eu(3+)证明了组装的可调谐性。这导致颜色特性得到了显著改善,为合理设计用于 SSL 应用的替代材料开辟了新途径。
