Intrinsic Broad-Band White-Light\nEmission by a Tuned,\nCorrugated Metal–Organic Framework

Abstract

Herein we report on the broad-band direct white-light\noriginating\nfrom a single component emitter, namely a novel three-periodic metal–organic\nframework (MOF). This material features an unprecedented topology\nwith (3,4)-connected nodes. The structure–function relationship\nin this system is driven by two complementary unique structural features:\ncorrugation and interpenetration. Good correlation between simulated\nand experimental emission spectra has been attained, resulting in\noptimized color properties that approach requirements for solid-state\nlighting (SSL). Guided by the optimized calculated spectra, the tunability\nof the assembly was proven by the successful in-framework co-doping\nof Eu³⁺. This resulted in significantly improved color\nproperties, opening new paths for the rational design of alternative\nmaterials for SSL applications.
