Drastic changes in photoluminescence properties of multilayer films composed of europium hydroxide and titanium oxide nanosheets

Abstract

Multilayer films consisting of Eu(OH)(3-x) and titanium oxide nanosheets showed strong Eu(3+) emission under UV-light irradiation, in which the titanium oxide nanosheet works as an antenna collecting UV-light, and then the Eu(OH)(3-x) nanosheet acts as an emitting layer receiving the absorbed energy.
