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.
