Rare earth ion‐exchanged zeolites exhibit a tremendous enhancement of luminescence upon treatment with suitable organic complexing agents, as reported here. For Eu 3+ exchanged zeolite X, the β‐diketone 1‐thienyl‐4,4,4‐trifluoro‐1,3‐butane‐1,3‐dione leads to the formation of intra‐zeolite complexes. Fully coordinated complexes within the supercages may be obtained by the additional coordination of 1,10‐phenanthroline (see Figure).
