Abstract

Abstract: In this study, lanthanide-doped zirconia powders with improved luminescent properties were prepared using a facile coprecipitation method. The morphology and structural properties of obtained powders were analyzed by using the field emission scanning electron microscope, X-ray diffraction, and magnetic properties measurement system, while their optical properties were investigated by room-temperature photoluminescence spectroscopy. We showed that codoping of Gd³⁺ into ZrO₂:Eu³⁺ could improve the emission intensity of ZrO₂:Eu³⁺ powders, and the emission peaks intensity varied with the codoping concentration of Gd³⁺. The possible mechanism leading to a luminescence enhancement in Gd³⁺-codoped ZrO₂:Eu³⁺ powders has been discussed. Graphical Abstract: [InlineMediaObject not available: see fulltext.]
