Abstract

Fluorescent semiconductor materials doped with rare earth ions have been synthesized by flocculation of colloidal titania nanosheets, Ti0.91O2, with Eu3+ or Tb3+ ions. The composites had a lamellar structure with a gallery height of 1.06nm, accommodating rare earth ions between the nanosheets with a doping concentration as high as 10±1mol%. The composite with Eu3+ exhibited intense characteristic emission from Eu3+ either by exciting the Ti0.91O2 host with UV light (λ&lt;350nm) or by directly exciting Eu3+ at a longer wavelength where there was no absorption by Ti0.91O2. This indicates that nonradiative energy transfer from the Ti0.91O2 host to Eu3+ can take place in this system. In contrast, no energy transfer was observed in the composite with Tb3+.
