Five luminescent tris(bipyridine)‐based cryptates with the lanthanoids Eu and Nd have been prepared with a systematic increase in the number of 2,2′‐bipyridine‐N,N′‐dioxide units and with different deuteration levels in the complexing cryptands for the europium species. Careful analysis of the radiativelifetime τrad in these systems reveals that an increase in N‐oxide units around the metal centers
