Novel bimetallic lanthanide metal–organic frameworks (Ln-MOFs) for colour-tuning through energy-transfer between visible and near-infrared emitting Ln3+ ions†
Abstract
A new family of isostructural bimetallic lanthanide metal–organic frameworks of M1−xNdxL2 (M = Eu, Tb, and Dy, 0 < x < 1, L = 2,5-pyridinedicarboxylate) was designed for color-tuning. The controllable color-tuning in the red, green and blue regions has been achieved through energy transfer from visible emitting Ln3+ to near-infrared emitting Ln3+.
