Long-lived emission beyond 1000 nm: control of excited-state dynamics in a dinuclear Tb(iii)-Nd(iii) complex

A long-lived near-infrared Nd(iii) emission is demonstrated using a Tb(iii) donor. The observed emission lifetime of 290 mu s at 1057 nm for a Tb(iii)-Nd(iii) dinuclear complex is attributed to the long-lived Tb(iii) donor and the appropriate spacing between the lanthanide ions. This design strategy leads to novel lanthanide photophysics.

Automated summary

A long-lived near-infrared Nd(iii) emission at 1057 nm is demonstrated using Tb(iii) as the donor, with an emission lifetime of 290 µs attributed to the appropriate spacing between the Tb(iii) donor and the Nd(iii) acceptor, leading to novel lanthanide photophysics.
