Abstract

Infrared-to-visible upconversion emission spectrum is investigated in Li⁺, Ho³⁺ and Yb³⁺ codoped Y₂O₃ nanocrystals. By adding Li⁺ ion to the Y₂O₃:Ho³⁺/Yb³⁺ nanocrystal, the upconversion emission intensity is found being significantly enhanced comparing with that without Li⁺ ion. The two reasons for this enhancement are discussed: one is because of the modification of the local symmetry of the Ho³⁺ ion, and the other is because of the reducing number of OH groups. This indicates Li⁺ ion would be a wonderful photoluminescence intensifier for rare-earth.
