A high-efficiency white light-emitting lanthanide-organic framework assembled from 4,4′-oxybis(benzoic acid), 1,10-phenanthroline and oxalate

The metal-organic frameworks, [Ln(oba)phen(ox)(0.5)](n) (H(2)oba = 4,4'-oxybis(benzoic acid), phen = 1,10-phenanthroline and ox = oxalate), have been designed and synthesized. The Eu(III)/Tb(III)-frameworks display highly efficient red/green emissions, respectively. A high-efficiency white light emission was realized through the doping of the Gd(III) framework with Eu(III)/Tb(III).
