Abstract

The intrinsic white-light-emitting properties of a lanthanide metal-organic framework that approach requirements for solid-state lighting are easily improved by incorporating minute quantities of red-emitting Eu(3+) into the host framework by virtue of the isostructural character of the La(3+) and Eu(3+) compounds and efficient sensitization of ligands toward Eu(3+) ions.

摘要

通过利用La(3+)和Eu(3+)化合物的同构特性以及配体对Eu(3+)离子的有效敏化作用,将微量发红光的Eu(3+)掺入主体框架中,可轻松改善接近固态照明要求的镧系金属有机框架的固有白光发射特性。
