Abstract

The upconversion photoluminescence of Ho³⁺ ion sensitized by Yb³⁺ ion in Ho³⁺/Yb³⁺codoped Gd ₂O₃ nanocrystals with and without Li⁺ is investigated in this paper. Strong fluorescence in the green (534-570â?nm) and red (635-674â?nm) regions of the spectrum has been observed, arising from the ⁵F₄/⁵S₂ â? ⁵I₈ and ⁵F₅ â? ⁵I₈ transitions of Ho³⁺ ion, respectively. Yb³⁺ ion is considered to be a better sensitizer for catching enough pumping energy and transferring considerable energy to Ho³⁺ in the Ho³⁺/Yb³⁺system. The upconversion intensity emitted by Ho³⁺ is greatly enhanced when Li⁺ is added to the Ho ³⁺/Yb³⁺ codoped Gd₂O₃ nanocrystals.
