Photochemical host–guest interaction in Tb3+ and Eu3+ ion-exchanged K2−xHxTi2O5 layered oxides

Abstract

Luminescence of Eu 3+ and Tb 3+ intercalated in K 2-x H x Ti 2 O 5 layered oxides is observed by exciting the layered titanate host indicating that the energy transfer via electron–hole trapping from the layered host to the guest in the interlayers occurred.
