Photochemical host–guest interaction in Tb³⁺ and Eu³⁺ ion-exchanged K_2-xH_xTi₂O₅ layered oxides

Abstract

Luminescence of Eu³⁺ and Tb³⁺ intercalated in K_2-xH_xTi₂O₅ 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.
