Abstract

This study examined the enhanced upconversion luminescence emission of bimodal Gd₂O₃:Er³⁺ particles by codoping with a trace amount of Li⁺ ions. Gd₂O₃:Er ³⁺/Li³⁺ composite particles with enhanced upconversion luminescence emission were synthesized by using a simple urea homogeneous precipitation method. The effect of the particle size and Er³⁺/ Li⁺ concentration ratio on the structural, morphological and optical properties of Gd₂O₃:Er³⁺/Li⁺ particles were studied systematically by X-ray powder diffraction, field emission scanning electron microscopy and room temperature photoluminescence. Strong upconversion eye-visible green light emission was observed from the Gd₂O₃:Er³⁺/Li⁺ particles under continuous near-infrared pump excitation from a commercially available diode laser. Monodisperse bimodal Gd₂O₃:Er³⁺/Li ⁺ particles show a good potential for biomedical and solid state lighting applications.
