Ho ho ho! Characteristic visible and near‐infrared (NIR) emission bands of the Pr III and Ho III complexes of the tetradentate 1‐methyl‐3‐hydroxypyridin‐2‐one chromophore are observed in aqueous solution. The Ho III complex has been structurally characterized and, for the first time for a Ho III complex, the kinetics of the luminescence decay in the NIR region have been determined in solution.
